The present invention relates to a fluid pressure cylinder comprising: a piston (18) to be able to change a location along the inside of a cylinder tube (12) which composes a fluid pressure cylinder (10); and a piston cover (22) which consists of an elastic material to cover the end of one side of the piston (18). The piston cover (22) comprises: a main body (50) to face a head cover (14) of the cylinder tube (12); a guide part (52) which is slid and in contact with the inner circumferential surface of a cylinder hole (28) by covering the outer circumferential surface of the piston (18); and a hook part (54) curved toward the inner circumference with respect to the guide part (52). Moreover, the main body (50) is in contact with the head cover (14) and absorbs impact when the position of the piston (18) is changed toward the head cover (14), and the guide part (52) is slid and in contact with the cylinder hole (28) when the position of the piston (18) is changed along the cylinder tube (12), so the piston (18) is guided along an axis. |
