PROBLEM TO BE SOLVED: To simultaneously reduce the machining cost of a base part of an output shaft and the assembly cost. SOLUTION: A base part 36A of an output shaft 36 of a magnification device is formed by a holder 43 separate from a rod member 36B, and a stopper 42 is formed separately from the holder 43. The holder comprises a bottom part 43A press-fitted in the rod member, a small diameter part 43B extending to the rear side from the bottom part, a stepped part 43C extending outwardly in the radial direction from the small diameter part, and a large diameter part 43D extending to the rear side from the stepped part. The stopper is press-fitted in the large diameter part, and protruded in the radial direction inward of the small diameter part. A coil spring 41 is disposed on the front side in the small diameter part, a piston 40 is disposed on the rear side thereof, the stopper is disposed on the front side in the large diameter part, and a reaction disk 35 is disposed on the rear side thereof. |
