In a fuel injection pump fixed to the pump body via a stop member in front of the stop member, the stop member has a straight part that engages with the guide pin, and a hook part formed by bending the straight part inward on both sides of the straight part. and a radiused portion formed by bending outward at the tip of each hook portion, and the pump body is configured such that each radiused portion of the stopper member is guided by elastic deformation of the stopper member. A fuel injection pump characterized in that a fitting groove is formed on both side surfaces of the stopper member, and the hook portion of the stopper member is fitted into the fitting groove with tension remaining thereon.
