。 A rod whose distal end side is inserted into the cylinder so that it can freely protrude and retract, and a stepped portion which is interposed on the outer periphery of the tip spigot part of the rod and whose rear end surface is formed at the boundary between the shaft part of the rod and the tip spigot part. In a piston fixing structure comprising a piston to be abutted, and a split ring interposed on the outer periphery of the distal end intervening portion of the rod and whose rear end surface is adjacent to the distal end surface of the piston, the split ring is It is formed to be tightened in diameter by tightening the tightening bolt, and is interposed on the outer periphery of the tip intervening part of the rod with an appropriate gap, and the inner periphery of the tip is connected to the outer periphery of the rod tip. What is claimed is: 1. A piston fixing structure, characterized in that the piston is adjacent to a stopper portion, and the adjacent surface between the stopper portion and the inner peripheral side of the tip is a tapered surface.
