A straddle-type vehicle (100) includes a frame (20) and an engine (10) mounted on the frame (20). The engine (10) includes a cylinder head (11) positioned toward the rear end of the frame, and located below a saddle seat. The cylinder head faces toward the rear end of the frame, which allows the heated cylinder head of the engine and the exhaust pipe connected to the cylinder head to avoid the position where the user's legs contact the vehicle while riding, so the effect of heat emitted from the cylinder head on the rider's experience is reduced.

A straddle-type vehicle includes a driver seat on which a driver rides, a cylinder head of an engine arranged in a region in front of and below the driver seat, an exhaust pipe that is connected to an exhaust port formed on a front surface of the cylinder head and exhausts exhaust of the engine, and a control unit that is arranged in an engine front space formed in front of the cylinder head, above the exhaust pipe, and below an upper end surface of the engine and controls the straddle-type vehicle.

A fuel tank includes an outer component including an outer panel forming a tank outer shell and an inlet plate formed separately from the outer panel, an inner component including an inner panel forming a tank inner shell and an inner connection plate formed separately from the inner panel, and a pipe passing through inside of the outer panel and the inner panel and connecting the inlet plate and the inner connection plate. The inlet plate is joined to the outer panel, the inner connection plate is joined to the inner panel, and the inner panel is joined to the outer panel.

A fuel tank includes a tank panel in which a storage space of a fuel is formed, a tank inlet fixed to the tank panel, and a tank cap that allows the tank inlet to be opened and closed. The tank inlet includes a bottomed cylindrical inlet plate to which the tank cap is attached, an inlet pipe that protrudes from a bottom wall of the inlet plate into the storage space, and a separator configured to separate the fuel entering from the storage space into a liquid component and a gas component. The separator is supported by the bottom wall of the inlet plate in the storage space, and the separator is disposed on an outer side of the inlet pipe and on an inner side relative to an outer edge of the inlet plate in a bottom view of the tank inlet.

An all-terrain vehicle includes a frame, an engine, an air filter, and a fuel tank. The frame includes a seat cushion and a steering handle. The engine is arranged on the frame and provides power. The air filter is arranged on the frame and coupled to the engine. The fuel tank is arranged on the frame and coupled to the engine. The air filter at least partially shields an upper surface of the fuel tank.

A rotary knob that rotates in a pushed state includes an extending portion extending in a rotation direction of the rotary knob, and the extending portion includes a cutout portion cut out so as to prevent a first switch that detects that the rotary knob is pushed in from being pressed in a case where the rotary knob is in an intermediate range in which the rotary knob is in a pushed state.
