する油圧シリンダ。 A cylinder head member is attached to one end of a cylinder tube in which a piston is slidably housed, and a piston rod integrally fastened to the piston is slidably supported by the cylinder head member, and the piston rod is opposed to the piston of the cylinder head member. A notched groove is formed on the end face, a cushion bearing is provided on the piston rod, and notched grooves are formed at each of the axial ends of the cushion bearing,
One end of this cushion bearing is brought into contact with the piston, and the other end is exposed to the gap on the inner periphery of the cylinder head member. When the piston moves and the cushion bearing enters the gap, the cushion effect is exerted in the hydraulic cylinder. , chamfered portions are formed on the inner and outer corners of the end surfaces of the cylinder head member facing the piston and on both axial end surfaces of the cushion bearing; A hydraulic cylinder characterized in that the dimensions are larger than the axial dimensions of each of the annular grooves.
