摘要： An automatic residual fuel vent device for a carburetor, the device including a fuel supply passage (15) connecting a fuel tank (TF) and a float chamber (10), a negative pressure passage (17) connecting an intake passage (8) and a negative pressure operating chamber (53) of a diaphragm pump (PD), a fuel vent passage (16) connecting the float chamber (10) and the fuel tank (TF), a single changeover cock (CO) provided so as to straddle the fuel supply passage (16) and the negative pressure passage (17), a negative pressure surge tank (TS) provided in the negative pressure passage (17), and the diaphragm pump (PD), which is connected to the fuel vent passage (16) and is operated by negative pressure of the negative pressure surge tank (TS), residual fuel of the float chamber (10) being returned to the fuel tank (TF) by the diaphragm pump (PD) operated by negative pressure from the negative pressure surge tank (TS) in accordance with the changing over of the changeover cock (CO). This enables residual fuel within the float chamber of the carburetor to be reliably returned to the fuel tank by intake negative pressure accumulated in the negative pressure surge tank and, furthermore, residual fuel can be vented by the changing over of a single changeover cock, thus enabling the number of components to be reduced and the device to be provided at a low cost.

摘要： A walk-behind tiller has a body and a pair of wheels mounted on the body for undergoing rotation to cause the walk-behind tiller to undergo travelling along a ground surface. A tilling device is mounted on the body for undergoing a first movement operation in which the tilling device travels along the ground surface while the tilling device is disposed in spaced-apart relation to the ground surface, a second movement operation in which the tilling device tills the ground, and a third movement operation in which the tilling device is maintained generally horizontal to the ground surface. A handle has proximal portions, a pair of grip portions connected to the proximal portions and configured to be gripped by an operator to maintain the tilling device generally parallel to the ground surface during the third movement operation, a pair of rising portions connected to the grip portions and configured to be tilted by the operator during the second movement operation to cause the tilling device to till the ground, and a cross portion disposed between the rising portions and configured to be gripped and pressed by an operator to produce a force tending to move the tilling device about the rotational axis to maintain the tilling device in spaced-apart relation to the ground surface.

摘要： Ball member is provided between a ball retaining member provided integrally with a driving rotational member and opposed axial end portions of left and right drive shafts, and a selection can be made as necessary between a non-differential operation mode where the drive shafts rotate substantially equally and a differential operation mode where the drive shafts rotate differentially. The retaining member has a through-hole portion to receive part of the ball member. Shift member is slidably fitted over the retaining member and includes a ball-restricting portion of an inner diameter generally equal to an outer diameter of the retaining member and a ball-releasing portion having a greater inner diameter than the restricting portion. Power-transmitting portions are provided on the opposed axial ends with which the ball member is engageable to transmit the driving power.

摘要： A differential device has a power-transmitting member mounted to undergo rotation in forward and reverse directions about a central rotational axis and to undergo linear movement in a direction along the central rotational axis. The power-transmitting member has meshing claws each having an inclined surface. A pair of driven shafts are mounted to undergo rotation about the central axis. A pair of rotational driven members have meshing claws confronting and for meshing engagement with the meshing claws of the power-transmitting member. When the power-transmitting member rotates to transmit rotational driving power to the driven members, force components acting on contacting surfaces of the meshing claws of the power-transmitting members and the driven members displace the driven members in an axial outward direction away from the power-transmitting member to define therebetween a space to allow axial movement of the power-transmitting member within the space.

摘要： In order to minimize unwanted corotation, a gear support member is in the shape of a flat disk and has an outer diameter greater than the pitch circle of a ring gear. Further, a surface level of lubricating oil stored in a casing is set to be below the ring gear, but above the gear support member. Furthermore, a resilient clip is resiliently fitted on an output shaft and gear support member, and the resilient clip has at least one end supported by the casing. In addition, the casing has, on its bottom, a frictional surface for sliding contact with the lower surface of the gear support member.

摘要： A continuously shifting-type steering system includes a pair of left and right hydrostatic continuously variable transmissions each of which is comprised of a hydraulic pump and a hydraulic motor, and a pair of left and right planetary gear mechanisms each having a first sun gear, a second sun gear, a two-step planetary gear and a carrier. A first driving gear connected to an engine, is operably connected commonly to the left and right first sun gears. Left and right second driving gears secured to motor shafts of the left and right hydraulic motors, are operably connected to the left and right carriers, respectively. Left and right output shafts are operably connected to the left and right second sun gears, respectively. Thus, it is possible to provide an increase in the shifting range of the continuously shifting-type steering system, and an enhancement in low-output performance.
