関用ピストンピンの係止構造。[Claims for Utility Model Registration] A piston pin that connects a piston and a connecting rod is inserted into a hole provided in the piston, and a locking member is fitted into a groove provided in the hole to fit the end surface of the piston pin. In a locking structure for a piston pin for an internal combustion engine that locks the piston pin to a piston by contacting the piston pin, the locking member includes a ring portion formed in an annular shape and a grip portion formed by bending one end of the ring portion. A locking structure for a piston pin for an internal combustion engine, characterized in that the gripping portion is bent at an acute angle toward the vicinity of the ring portion from a line connecting the annular center of the ring portion and the bent portion.
