Claims

[Claims for Utility Model Registration] 1. A cylinder tube whose both ends are closed, a piston movably provided within the cylinder tube, and a portion of which is connected to the piston so as to move together with the piston tube. In a device for stopping the piston in an intermediate position, the device is used for a rodless cylinder that is equipped with a piston yoke projecting to the outside of the piston tube, and the movement of the piston is taken out of the piston tube via the piston yoke. A brake guide extending along the cylinder tube is fixed to the yoke, a movable table is attached to the yoke, and a brake arm that presses the brake guide at one end near the brake guide is rotatable on the movable table. The movable table has a cylinder hole extending in the axial direction of the cylinder tube, and a brake piston is installed in the cylinder hole. An intermediate stop device for a rodless cylinder, characterized in that the piston is movably provided, and a roller is attached to the piston to engage with the inclined surface of the brake arm. 2. An intermediate stop device for a rodless cylinder according to claim 1, wherein the inclined surface formed in the brake arm is defined by a slot formed in the brake arm, and the roller is inserted into the slot.
