摘要： PROBLEM TO BE SOLVED: To increase the degree of freedome of an engine position on a car body and mount an engine in a position, where excellent vehicle weight distribution is effected, without impairing a proper drive sprocket position on the drive wheel side and a driver position. SOLUTION: A small vehicle 1 loads an engine 40 on a car body and fetches a power from a crankshaft 53, pivotally supported at the crank cases 51 and 52 of the engine 40, by a power fetching shaft 41, and transmits the power from the power fetching shaft 41 to the drive wheel side. In this case, both sides of the power fetching shaft 41 are supported through bearings 100 and 101 and a power from the crankshaft 53 is inputted between the two bearings 100 and 101. By selecting one of the two end sides of the power fetching shaft 41, a power is transmitted to the drive wheel side.

摘要： PROBLEM TO BE SOLVED: To increase the degree of freedom of an engine position in a vehicle body and facilitate ensurance of a driver area, and mount an engine in a position, wherein vehicle weight distribution is excellently effected, without impairing a sprocket position on the proper drive wheel side and the driver position. SOLUTION: A small vehicle loads an engine 40 on a car body, a power from a crankshaft 53 pivotally supported at the crank cases 51 and 52 of an engine 40 is fetched by a power fetching shaft 41. A power is transmitted to the drive wheel side from a drive sprocket 42 arranged on the power fetching shaft 41. In this case, the vicinity of a crank case part 51a to cover the crank web 53a of the crankshaft 53 is recessed to form a space 99 and the drive sprocket 42 is arranged in the space 99.

摘要： PURPOSE:To prevent fixing of tar an so on to between a valve and a storage recess part in an exhaust device of a two-cycle engine in which exhaust timing is controlled through arrangement of the valve in the storage recess part formed in the neighborhood of a main exhaust port by projecting a partition wall between an auxiliary exhaust passage and a main exhaust passage into the storage recess part. CONSTITUTION:A main exhaust port 3d and a pair of auxiliary exhaust ports 3e are opened at the part upper than a scavenge port 3c of a cylinder 3a in a two-cycle engine 1, and a storage recess part 11 is formed at the lower stream part adjacent to the main exhaust port 3d of a cylinder body 3 so that it crosses the upper part of a main exhaust passage 3f. And a valve 12 is rotatably inserted and arranged in the storage recess part 11 so as to make exhaust timing variable by rotating it according to an engine revolution number. In this case, a partition wall 3h forming a boundary between the main exhaust passage 3f and an auxiliary exhaust passage 3g is extended inward to a circular part 11b of the storage recess part 11 and projected into the circular part 11b. By this, exhaust gas is restrained from flowing from the main exhaust port 3d through a gap between the valve 12 and the storage recess part 11, and fixing of tar an so on is prevented.

摘要： PURPOSE:To prevent the interference with a caliper by forming a silencer from a cylindrical body which becomes gradually thinner towards the rear side of a car body and setting the lower edge of the silencer nearly parallel to the upper edge of the caliper at the uppermost position of a rear wheel, viewed from the side surface. CONSTITUTION:A silencer 15 is formed by a cylinder body which becomes gradually thinner towards the rear side of a car body. The lower edge of the silencer 15 is set parallel to the upper edge of a caliper 9 at the highest position of a rear wheel, viewed from the side surface. Accordingly, the interference with the caliper 9 is prevented, and the capacity can be increased by that thicker portion of the front side part in comparison with the rear side part, even if the silencer 15 is not made long in the longitudinal direction.

摘要： PURPOSE:To prevent a motorcycle itself and other motorcycles from being polluted by exhaust drain from the motorcycle itself by arranging a drain exhaust hose connected to the rear and lower part of an exhaust pipe, through a space above a rear wheel, inside a license bracket, and forming an opening downward therefrom. CONSTITUTION:A tail cowl 7 is provided behind the passenger seat 6 of a motorcycle, while a mud guard 10 and a license bracket 11 are installed below those components respectively. Further, below them are disposed the tapered pipe 17b and the straight pipe 17c of a muffler pipe composing an exhaust pipe respectively. A drain exhaust hose 25 is connected to a short pipe 24, which is connected to the straight pipe 17c in this constitution. The drain exhaust hose 25 is arranged inside a license supporting part 11b through the inner part of a direction indicator 26 attached on the license bracket 11, then the rear end opening of the hose is arranged on the lower end of the license supporting part 11b.

摘要： PURPOSE: To guide an overflowing fuel to a desired position by installing an elastic guide member on a flange connection part, and forming a fuel guide passage in it in a fuel tank comprising an upper and a lower tank members connected to each other at flanges formed at peripheries of them. CONSTITUTION: A fuel tank 14 disposed roughly at a center part of a subsidiary frame 2b of a steel pipe extended diagonally upward to compose a car body frame of a motor-bicycle is composed by connecting a plate-shaped upper tank member 15 and a lower tank member 16 respectively having flange parts 15a, 16a at peripheries at the flange parts 15a, 16a to each other. In this case, a guide member 17 of rubber having a roughly U-letter shaped plan view is installed on a flange 14 (15a, 16a) of the fuel tank 14. A circumferential wall 17a extended upward is formed on a outer circumferential edge part, and a flange installation groove 17b is formed on an inner circumferential surface in the guide member 17. A hose 18 is connected to an insertion hole 17d formed in a curvature part 17f of the guide member 17 for communication.

摘要： PURPOSE:To improve strength and to shorten a longitudinal length by forming a silencer with an extrusion-molded member having a body part and a pipe part and causing the pipe part to form a strength member for intercoupling a seat rail and a rear arm bracket. CONSTITUTION:A motorcycle 1 has a silencer 17 located between a seat rail 4 and a rear arm bracket 5. In this case, the silencer 17 is formed by integrally molding a body part 17a and a pipe part 17b through extrusion of aluminum. Back stays 19 respectively mounted to the seat rail 4 and the rear arm bracket 5 are inserted in both ends of the pipe part 17b for welding. This constitution utilizes the body part 17a and the pipe part 17b as respective strength members, improves the strength and rigidity of the silencer 17, and obliquely disposes the body part 17a to shorten the longitudinal length of the silencer 17.
