ダ。 A piston head fixed to the inner tip of the piston rod is slidably built into the cylinder hole of the cylinder barrel, and a cylindrical lock piston is inserted between the outer peripheral surface of the inner tip side of the piston rod and the cylinder hole via a spring between the piston head and the piston head. Slidable and without,
A locking piston is fixed to the open end of the cylinder barrel and parallel to the outer circumferential surface of the piston rod, between the stepped portion provided on the inner circumferential surface of the lock piston on the open end side of the cylinder barrel and the inclined cam surface provided around the outer circumferential surface of the piston rod. The piston rod has a structure in which the extension of the piston rod is restricted by inserting and clamping the tip of a plurality of lock fingers disposed around the circumference. A hydraulic cylinder with a lock, which has two stages and has a large pressure-receiving area on the piston head side of the lock piston that slides on the same part.
