Abstract
A fuel pump includes a holed disk-shaped plate and a coil spring to press the plate toward a lifter. The plate has an inner circumferential surface to be engaged with a groove in a projection-side end portion of a plunger. Also, a joint port that connects the inner peripheral surface of the plate to an outer peripheral surface thereof is provided in the plate. The coil spring is located between the plate and a pump body. The plate is assembled in the fuel pump to dispose the joint port at a position in an opposite direction to the direction of a side force to be generated during compression of the coil spring when viewed from a central axis of the coil spring.
