摘要： PURPOSE: To prevent an absorption effect from being degraded caused by the occurrence of gaps as absorbing agent is pulmerized by increasing the degree of freedom in mounting with a casing simplified in shape, and concurrently enhancing the property of mass production in the transverse type canister where the flow direction gas in the inside of a casing is roughly horizontal. CONSTITUTION: A movable support plate 121 is so constituted as to be inclined to a side which is parted from a stationary filter 10 as it goes upward.

摘要： PURPOSE: To avoid the inclination of a filter and a support plate and to prevent the lowering of adsorbing efficiency by providing an inclination hindering part over the filter and the support plate, which are provided in the bottom of a casing. CONSTITUTION: At the time of non-supplying of fuel such as a parking time of a vehicle, the evaporative fuel guided by an evaporative fuel guide pipe 38 is adsorbed by the adsorbent in first adsorbent layers 291 , 292 and a second adsorbent layer 30. In such a canister, the first adsorbent layers 291 , 292 and the second adsorbent layer 30 are elastically held by a spring 32 between first filters 241 , 242 , a second filter 25 and a third filter 28. At this stage, an inclination hindering part 211 is provided in a casing main body 17 with a space, which nearly corresponds to the space between the third filter 28 and the partitioning wall 19, between the third filter 28. Even in the case where the third filter 28 and the support plate 27 try to be inclined around a part corresponding to the partitioning wall 19, the inclination is hindered, and a fall of the adsorbent to a third chamber 31 with the inclination of the third filter 28 and the support plate 27 can be securely prevented so as to maintain the adsorbing efficiency.

摘要： PROBLEM TO BE SOLVED: To provide an oil feed pipe for a fuel tank which can smoothly feed oil. SOLUTION: The oil feed pipe 2 with one end thereof connected to the fuel tank 1 and with an oil feed gun insertion part 4 provided on the other end thereof has a double pipe structure comprising a small diameter pipe 5 of the diameter substantially as large as that of the oil feed gun 3 and a large diameter pipe 2a to surround the small diameter pipe so as to form a flow passage 6 to allow the fuel overflowing from the small diameter pipe to flow as the oil is fed between the small diameter pipe and the large diameter pipe. The high flow rate of the fuel in the small diameter pipe can be kept when the fuel is fed, and the fuel in the entire fuel pipes can be sucked into the fuel tank by the merging with the fuel which overflows from the small diameter pipe and flows in the flow passage between the small diameter pipe and the large diameter pipe at an open end part on the tank side of the small diameter pipe. Oil can be smoothly fed by this suction effect. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To allow fuel vapor in supplying fuel to be sent to a canister by increasing the positional energy of supply fuel when a difference between a fuel supply port and a liquid level of the fuel in a tank is larger, to thereby raise the energizing ability of residual air in the tank, and to supply the fuel even when ventilating resistance is increased by connecting an air tube, that is an evaporating fuel passage, to the canister. SOLUTION: The fuel vapor in supplying the fuel is directly exhausted to the atmosphere through a breather in a truck. A fuel tank structure for the truck comprises the fuel tank 13 disposed under a floor 15 of a luggage carrier, a hole 19 opened at a floor 1, a fuel supply tube 14 extended upward via the hole 19, and the fuel supply port 14a having a fuel supply cap disposed preferably on a saddle plate 16.

摘要： PROBLEM TO BE SOLVED: To prevent the outward spatter of a splashed fuel upon automatic fill-up stoppage of high speed fuel feeding. SOLUTION: A funnel partition wall 5 having a nozzle insertion hole 5a is provided in a feeding gun insertion portion 4, an air vent port 6 is provided in the tapered peripheral wall of the partition wall, and a baffle 7 for shielding the air vent port at its fuel tank side and at both sides is fixed thereinto at its three portions. The air vent port is provided separately from a gap between a nozzle and the nozzle insertion hole for preventing the jump of the splashed fuel out of those portions, and the baffle is provided in the air vent port to form a simple labyrinth structure for preventing the outward jump of the splashed fuel via the air vent port. Thus, the outward jump of the splashed fuel, when forcibly splashed back at automatically stopping fill-up of the tank during high speed feeding, is effectively prevented. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To prevent an oil feed pipe or a vaporized fuel return pipe from being broken by any deformation of the oil feed pipe accompanied by the deviation or the assembly work caused by fitting errors between a connection part on a body panel side of the oil feed pipe and a fuel tank. SOLUTION: One end of the oil feed pipe 4 and one end of the return pipe 7 to return the air mixed with fuel vapor are connected to an upper part of the fuel tank 3, the other end of the oil feed pipe 4 is connected to the body panel 6 via an oil feed gun insertion part 5, and the other end of the return pipe is connected to the oil feed gun insertion part 5. A loop-shaped buffer part 8 in plan view is provided on a middle part of the oil feed pipe, and a similar buffer part for the return pipe is also provided on a middle part of the return pipe. Even when the fuel tank is displaced during the assembly, and the oil feed pipe is deformed by the relative displacement between the connection part on the body panel side of the oil feed pipe and a connection part on the fuel tank side, the deformation can be absorbed by the buffer part, and the oil feed pipe is not broken. The return pipe is not broken, either. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To provide an intake and exhaust structure for a canister, which prevents a reduction in opened area of an exhaust opening resulted from icing of water penetrated thereinto. SOLUTION: In the middle of an intake passage 21 leading from the outside to a canister 14 a one-way valve 23 is provided, and an intake opening 21a of the intake passage is located in a side frame 1 sectionally closed. In the middle of an exhaust passage 25 leading from the canister to the outside an one-way valve 27 is provided, and an exhaust opening 25a of the exhaust passage is located in a sub frame 5 sectionally closed. Outside water or mud is hard to invade the side and sub frames. When the canister absorbs evaporated fuel coming from a fuel. tank generated in fuel-filling, the air of which evaporated fuel compositions are absorbed emitted from the canister is emitted out of the exhaust opening to the outside. When the canister feeds evaporated fuel compositions thus purged to an engine, fresh outside air is inspired from the intake opening through the intake passage to the canister.

摘要： PURPOSE: To avoid the inclination of a support plate and to prevent the lowering of the absorbing efficiency by engaging projecting and recessed parts, which are provided in the inner surface of a casing, with recessed and projecting parts, which are provided in the periphery of the support plate, freely to be slid in the vertical direction. CONSTITUTION: At the time of non-supplying of fuel such as a parking time of a vehicle, the evaporative fuel guided by an evaporative fuel guide pipe 38 is adsorbed by the adsorbent in a first adsorbent layer 29 and a second adsorbent layer 30. In such a canister, the first adsorbent layer 29 and the second adsorbent layer 30 are elastically held by a spring 32 between a first filter 24, a second filter 25 and a third filter 28. At this stage, since plural fitting projecting parts 421 , 422 , which are provided in the inner surface of a casing main body 171 , are fitted in plural recessed parts 431 , 432 , which are provided in the periphery of the support plate 271 , through the support plate 271 can move in the direction for compressing both the adsorbent layers 29, 30 within the casing main body 171 , the change of the posture of the support plate 271 , to the inclination side is hindered. Consequently, the fall of the adsorbent to a third gas chamber 31 with the inclination of the third filter 28 and the support plate 27 can be securely prevented.
