止機構。 A piston with a piston rod is slidably installed inside the cylinder tube, a sealing member is provided on the outside of the cylinder tube, the piston rod is passed through the sealing member, and the sealing member seals the penetrating part of the piston rod to prevent dust from entering the cylinder. In the mechanism, a dust seal is provided on the outside in the axial direction of the seal member, a pressure chamber is defined between the opposing parts of the two, a supply path for supplying pressure fluid is connected to this pressure chamber, and the pressure chamber is connected to the outer periphery of the piston rod. A cylinder dust intrusion prevention mechanism configured to open to the outside through a gap between the cylinder and the dust seal.
