A C-shaped clip 54 is set on the outer periphery of a shaft section 21 of a guide member 2. Part of the C-shaped clip 54 is held between a front edge of a clamp member 3 and the shaft section 21 by gripping a lever 4. In this case, the C-shaped clip 54 is held slantwise to situate the lower end thereof in front. Then, the shaft section 21 of the guide member 2 is inserted into a piston pin installation hole 51 of a piston. In this manner, the lower end of the C-shaped clip 54 is first fitted into an annular groove 53. If the shaft section 21 is further driven to advance while releasing the lever and releasing the holding condition by the clamp member 3, the rest of the C-shaped clip 54 is pushed into the annular groove 53 by a step section between the shaft section 21 and a joint section 22.
