ランプ装置。In a clamping device such as an indexing table using a hydraulic cylinder in which the table is moved in the axial direction of the piston as the piston moves and is clamped by hydraulic pressure at the moving end, the hydraulic cylinder is connected to a large diameter cylinder. A cylinder part consisting of small diameter cylinders stacked with their axes aligned, an integrated piston with a stepped shaft shape fitted into the two cylinders, and a piston in which pressure oil is sent to the outer chamber of the small diameter cylinder. A tank for replenishing oil into a chamber on the small diameter cylinder side of the large diameter cylinder when the piston is sent communicates with the outer chamber of the small diameter cylinder and the chamber on the small diameter cylinder side of the large diameter cylinder immediately before the piston movement end. a flow path provided in the piston, and an electromagnetic valve that shuts off the flow path between the tank and a chamber on the small diameter cylinder side of the large diameter cylinder immediately before the piston moving end. clamping device.
