摘要： A high-pressure fuel pump of a simple construction is capable of distributing the position of contact between a tappet and a cam so as to improve durability of the tappet without causing seizure of a piston. A cylinder is arranged in a housing, and the piston is received in the cylinder for sliding reciprocation so that fuel is sucked into the cylinder and pressurized by the piston. The tappet is arranged inside one end of the housing for reciprocation, and contacts the cam, which rotates with a camshaft of an engine, so as transmit a driving force of the engine to the piston. A sleeve is arranged between the tappet and the housing, and clearance fitted to an outer peripheral surface of the tappet and an inner peripheral surface of the housing. The tappet is caused to rotate on its own axis by a frictional force generated between the cam and the tappet.

The shaft is rotatably provided across an intake passage. The throttle valve is fixed to the shaft. The final spur gear is fixed to an end portion of the shaft. The drive motor applies a rotational force to the final spur gear. A full closure stopper determines a full closure position of the throttle valve, and full opening stopper determines a full opening position of the throttle valve. The final spur gear is provided with the collision portion, which collides with the full closure stopper and the full opening stopper to stop rotation of the final spur gear. The collision portion has a notch portion formed therein, defining a full-closure-side collision member that is elastically deformed through collision with the full closure stopper and a full-opening-side collision member that is elastically deformed through collision with the full opening stopper.
