Abstract

PURPOSE:To reduce the acceleration exerted on a piston during braking action on the piston by forming a damper insertion hole in a cylinder cap or a piston, and inserting a bar-shaped rubber damper in the damper insertion hole with a clearance in radial direction. CONSTITUTION:A damper insertion hole 29 comprising a large diameter hole 31 and a small diameter hole 35 is formed in a cylinder cap 7. A rod-shaped rubber damper 37 is inserted in the damper insertion hole 29 with a clearance in radial direction. Since the length of the rod-shaped rubber damper 37 occupies a large rate in comparison with the cross-sectional area, and the axial deformation quantity becomes large even if the same compressing force is applied thereto, furthermore, since an expansion displacement is formed freely, in the radial direction the projecting quantity, from the end surface of the cylinder cap 7, of the rod-shaped rubber damper 37 can be increased. Thus the acceleration exerted on the piston 15 during braking action on the piston can be reduced.
