ABSTRACT:
A device for mounting a cushion plunger to one end of the piston rod in a hydraulic cylinder, the cushion plunger constituting a part of a cushion mechanism installed to dampen the impact generated during the rotation of the piston in the hydraulic cylinder. The mounting device includes a recess provided at the end of the piston rod and adapted to partially receive the cushion plunger, a pin hole provided at the piston rod, the pin hole extending in a direction orthogonal to the recess such that it communicates with the recess, another pin hole perforated throughout the cushion plunger radially of the cushion plunger, the pin holes being aligned with each other at a state that the cushion plunger is received in position in the recess, a fling pin inserted into the pin holes being aligned with each other, the fling pin being adapted to fix the cushion plunger to the piston rod, and a clearance defined between the outer diameter of the fixing pin and the inner diameter of the pin hole of the cushion plunger.
