Abstract
A piston is provided displaceably in the interior of a cylinder tube that constitutes a fluid pressure cylinder, and a piston cover made from an elastic material is disposed so as to cover one end surface of the piston. The piston cover comprises a main body portion confronting a head cover of the cylinder tube, a guide portion covering an outer circumferential surface of the piston and disposed in sliding contact with an inner circumferential surface of a cylinder hole, and a hook portion folded toward an inner circumferential side with respect to the guide portion. Upon displacement of the piston toward the head cover, shocks are absorbed by abutment of the main body portion against the head cover. When the piston is displaced along the cylinder tube, the guide portion serves to guide the piston in the axial direction by sliding contact with the cylinder hole.
