A saddle-ride type vehicle includes an air-cooled fuel cell unit that is mounted on a body frame behind a head pipe and in front of a pivot frame and uses taken-in outside air for supplying oxygen and cooling a unit. The fuel cell unit includes an outside air intake open forward below the head pipe and an exhaust port open rearward above a pivot. A seat frame has a monocoque structure also having a configuration of an exhaust duct for guiding exhaust gas from the fuel cell unit to a back of an occupant's seat. Accordingly, in the saddle-ride type vehicle, it is possible to realize more efficient ventilation in utilizing a fuel cell.

In a structure for installing a fuel pump in a fuel tank, in which the fuel pump is attached to the fuel tank by clamping a flange portion of a pump case of the fuel pump between the fuel tank and a retainer fastened to the fuel tank, an interference portion is formed integrally with an inner peripheral edge of the retainer while being overhung inward in a radial direction, the interference portion being capable of interfering with any one of protruding portions when a relative position in a peripheral direction of the retainer with respect to the flange portion is set at a non-normal position, and a non-normal surface of opposite surfaces of the retainer is faced to the flange portion.

A snowmobile frame includes a tunnel, an engine cradle, a front suspension, a forward support and a fuel tank having a lower and an upper wall connected together 5 to enclose a volume. The volume fluidly communicates with the engine and has a portion extending upwardly and forwardly from the tunnel to the forward support. The fuel tank is removably connected to the tunnel and the forward support by the upper wall which has a left and a right lower end portion respectively connected to the tunnel on a left and right side of the longitudinal centerplane, and an upper end 10 portion connected to the forward support. The lower wall is connected to the upper wall above lower end portions and below the upper end portion. A force transmitted between the forward support and the tunnel, via the fuel tank, is transmitted through the upper wall without passing through the lower wall.

An electronic component is integrated into a vehicle body component, such as an automobile, a bicycle, etc., and may be an electronic lighting material and/or an electronic sensor. The vehicle body component is formed of multiple layers of a composite material that may be assembled to take the shape of a mold of a particular vehicle component. A sensor or lighting device is disposed in a void formed in the one or more of the layers of the composite material, and this device may be enclosed in the void by other layers. The lighting material and/or sensing mechanism are configured to connect to a power source via electrical wiring that is disposed either between or through the composite layers that form the vehicle body component and the vehicle body component is then cured to form a hardened vehicle body part with the sensor or lighting device formed therein.

A motorcycle includes an internal combustion engine, a frame, a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and a container connected to the internal combustion engine and the fuel tank. The container is configured to store fuel evaporating from the fuel tank, and the container in a position of use is at least partially covered by the fuel tank. The fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use.
