摘要： A sintered cam ring is secured to the inner surface of a cylindrical body by means of a bolt. A fuel injection pump has a rotor which supports a roller rotating along the inner surface of the sintered cam ring and is driven by an engine. The sintered cam ring is provided in the outer surface thereof with a groove extending along the central axis thereof. A positioning member for fixing the position of the groove and that of a pin hole formed in the body for receiving a bolt is inserted such as to stretch between the groove and the pin hole. Further, a bolt is employed to secure and tighten the positioning member fitted in both the pin hole and the groove from the outside of the body.
