In a fuel injection pump, a tappet is provided on an end thereof on a side of a cam ring with a hollow. Force acting on the tappet from a plunger due to fuel pressure is dispersed to a sliding contact surface outside the hollow so that contact face pressure between the tappet and the cam ring is smaller. As the fuel pressure becomes higher, larger resilient deformation of the tappet causes a diameter of the hollow smaller so that the tappet comes in flat slidable contact with the cam ring, resulting in preventing the contact portion between the tappet and the cam ring from being seized with frictional heat.
