A motorcycle has a large accommodating space and an enlarged capacity of a fuel filter. The motorcycle includes: a fuel tank disposed on the upper side of the rear wheel and on the rear side of the luggage box; a rear fender provided between the rear frames and, disposed between the luggage box and the rear wheel, and covering the rear wheel on the front and upper sides of the rear wheel; a fuel supply path; and a fuel secondary filter. The rear fender is so disposed that its front portion faces a rear wall of the luggage box, the front portion is inclined rearwardly upward so that the distance thereto from the rear wall increases along an upward direction, and the fuel secondary filter is disposed between the rear wall of the luggage box and the front portion of the rear fender.

A fuel tank structure including a fuel tank, a fuel filler port device formed in a cylindrical shape and arranged in the fuel tank, and a flame arrester arranged in the fuel filler port device and disposed inside the fuel tank. A fuel bleeding opening is formed in a peripheral wall part of the fuel filler port device and an arrester peripheral wall part. A cylindrical ring disposed so as to urge itself against the peripheral wall part and block the fuel bleeding opening.

Fuel tank structure

A scooter-type vehicle can freely set a capacity of a fuel filter without being restricted by swing of a unit-swing type engine. A cross pipe is spanned between a pair of left and right lower frames and a lower end of a down frame is connected to a central portion of the cross pipe. A fuel filter is disposed so that its lower end is higher by distance than the lower end of cross pipe. The fuel filter is disposed between the down frame and the fuel tank. Since the fuel filter is disposed in front of the fuel tank, it is not restricted by the swing of an engine located rearward of the fuel tank. Therefore, a capacity of the fuel filter can freely be set.

Scooter-type vehicle

A male terminal is provided in a terminal hole formed in a flange unit. A female terminal and a grommet having a sealing portion to be fitted into the terminal hole are provided to a harness. A distance from an end of the sealing portion to a fore-end of the female terminal is set smaller than a distance from a fore-end of the male terminal to an opening of the terminal hole. With such setting, the grommet is retained in the terminal hole even if the female terminal is disconnected from the male terminal, thereby ensuring support of the female terminal. Moreover, a stopper is attached so as to cover the terminal hole to prevent the grommet from slipping out of the terminal hole.

Fuel supply device

A scooter-type vehicle can freely set a capacity of a fuel filter without being restricted by swing of a unit-swing type engine. A fuel supply device includes a fuel tank and a fuel supply passage for supplying fuel to an engine. A pump-anterior filter for purifying the fuel in the fuel tank, a fuel pump, a fuel filter disposed on the downstream side of the fuel pump, and an injector for injecting fuel are arranged on the fuel supply passage in this order. The fuel filter is disposed between the upper surface of the fuel tank and the step floor. The size of the fuel filter can freely be set without being restricted by swing of the engine located rearward of the fuel tank.

Secondary fuel filter () provided downstream of a fuel pump () has a smaller pore size than a primary fuel filter () provided upstream of the fuel pump. The secondary fuel filter is covered with a case member () and positioned along a center frame () of the vehicle. The secondary fuel filter is made of non-woven fabric and formed in a bag shape, and fuel is filtered by the secondary fuel filter as it passes from the interior to the outside of the filter.

An aluminum-beryllium-silicon based alloy is disclosed, which comprises 5.0 to 30.0 mass % of Be, 0.1 to 15.0 mass % of Si and 0.1 to 3.0 mass %, the balance being Al and inevitable impurities. The alloy is useful for producing automobile engine parts, etc.

Aluminum-beryllium-silicon based alloy

A sliding surface of at least one of sliding members sliding with respect to each other in a sliding direction comprises a protrusion extending along a direction intersecting the sliding direction and fine dimples provided on a surface of the protrusion. In the sliding members, lubricating oil is accumulated in the dimples, and is easily extracted through a drain portion formed by dimple in a running-in operation.
