Claims

[Scope of utility model registration request]

A pump housing, a plunger housed in the pump housing so as to be reciprocally movable, a camshaft for driving the plunger housed in the pump housing so as to be axially removable, and a spring on the cam surface of the camshaft. a tappet that is slidably pressed against the biasing force of the cam surface and converts the rotation of the cam surface into reciprocating motion and transmits it to the plunger, and an opening is provided in the peripheral wall of the pump housing between the tappet and the cam surface. A through hole is opened, and a jig that contacts the end surface of the tappet on the camshaft side is rotatably inserted into this through hole, and by rotating this jig within the hole, the tappet is rotated. In a fuel injection pump that is moved in a direction away from a camshaft, the jig has a cylindrical main body that is rotatably inserted into a through hole, and a cylindrical body that is eccentric to the axis of the main body. An eccentric hole is formed through the hole at the position, and a rotating shaft is rotatably inserted into the eccentric hole, and one end of the rotating shaft led out from the eccentric hole is slid onto the camshaft side end surface of the tappet. A tappet moving device for a fuel injection pump, characterized by being provided with an eccentric cam in contact with the tappet.
