クツシヨン機構。 At the end of the stroke of the piston, a cushion ring fixed to the piston side is fitted into a hole provided on the cylinder side, and the fluid in the cylinder chamber is slightly dispersed between the outer circumferential surface of the cushion ring and the inner circumferential surface of the hole. What is claimed is: 1. A cushion mechanism for a fluid pressure cylinder in which fluid flows out through a gap, characterized in that a floating ring that limits the hole is attached to the cylinder side via an elastic body so as to be freely floating.
