ることを特徴とするピストン。[Scope of Claim for Utility Model Registration] A piston pin is inserted into a pin hole of a piston to connect connecting rods, and a circlip is attached to a ring-shaped groove formed at both ends of the piston pin in the pin hole to connect the piston pin. In the piston that prevents the piston from coming off, hook portions provided at both ends of the ring portion of the circlip are formed by bending the ring portion to a chamfer angle greater than the chamfer angle of the piston pin, and the hook portion is accommodated in the pin hole. A notch is formed in communication with the groove of the circlip, and when the hook part of the circlip is installed with the hook part protruding toward the side opposite to the piston pin, the entire circumference of the ring part is cut into a chamfered part at the end of the piston pin. A piston characterized by being in contact with.
