Claims

[Claims for Utility Model Registration] 1. Fixing of a piston to a piston rod in a double rod type cylinder in which the piston is fixed to a piston rod that extends in both directions and can reciprocate by passing through both covers provided at both openings of a cylinder tube. The structure is such that a retaining ring fitting groove is formed on the outer circumferential surface of the piston rod, the piston is fitted onto the outer circumferential surface of the piston rod, and the retaining ring fitted in the retaining ring fitting groove prevents the piston from coming out. A structure for fixing a piston to a piston rod in a double rod type cylinder characterized by a stop. 2. The double rod type cylinder according to claim 1, wherein a split ring and a split ring retainer are interposed between the end surface of the piston and the retaining ring fitted in the retaining ring fitting groove. Piston fixed structure.
