In the piston rod, an engagement head portion in which an engagement portion is formed is provided at the tip of the piston rod, and a compression piston that moves backward by abutting against the engagement head portion near the retreating end of the engagement head. A dynamic pneumatic cylinder is provided, an engagement cylinder having an engagement rod that is engageable with the engagement portion at a retracted end of the engagement head, and a pneumatic chamber of the pneumatic cylinder and the engagement cylinder. The cylinder chamber of the engagement cylinder is connected to an exhaust switching valve, and when the engagement head reaches a retreating end, the air in the pneumatic chamber of the pneumatic cylinder is fluidly connected to the cylinder chamber of the engagement cylinder. The shock absorber is configured such that the rod is compressed and flows into the cylinder chamber of the engaging cylinder, and the engaging rod protrudes and engages with the engaging portion.
