Claims

[Scope of utility model registration request]

In a cylinder in which a port is formed in each of a head cover and a rod cover attached to the end of a cylinder tube, and fluid is supplied from one of these ports to move a piston in the cylinder tube, the piston is prevented from rotating. The mounting position of the cushion pin is regulated so that the end of the slideable cushion pin supported by the piston approaches and moves away from the end of the port, and the cushion pin is slidable in the axial direction by the piston at both ends of the cushion pin. A stopper number is provided to regulate the amount, and the formation position of the stopper is adjusted so that when the piston contacts the cover and fully closes the port at the end of the cushion pin, a gear loop is formed between the stopper and the piston. The cushioned cylinder is provided with a cushion port provided in each of the head cover and the rod cover to communicate the port with the inside of the cylinder tube.
