PURPOSE: To cope with a controller for the axial movement of a fastening piston to make it adjustable with a simple method in adjusting a limit of the fastening piston stroke. CONSTITUTION: In a fastening device comprising a rotating fastening cylinder 1 and a controller 12 for the axial movement of a fastening piston 2, the controller comprises a first connecting part 13.1 and a connecting member 14.1 operating at a front end position of the fastening piston stroke by the connecting part, the connecting member is connected to a distibutor casing 5, and the connecting part is mounted on a connection rod 16.1. The connection rod is guided in the axial direction movably in the longitudinal direction while contacted with the casing 5, and fixed to a cylinder 1 to the relative axial movement by using a rotary bearing 17.1 mounted in the cylinder 1. The controller 12 further comprises a second connecting part 13.2, and the connecting part operates a second connecting member 14.2. |
