A first washer and a second washer (62, 64) respectively are arranged on both end sides (18a,18b) of a piston (18) which constructs a fluid pressure cylinder (10) component through composition slots (54a,54b),the first washer and the second washer (62,64) are formed by metallic material and elementary hollow of a cylindrical shape which is processed by pressure, where in, the washers (62,64) achieve cushioning action, translational speed of the piston (18)is reduced caused by the washers (62,64) are moving along axis at the same time and accept and accommodate in a concave (24) of a cylindercover (14) and a pole hole (34) of a pole cover (16).
