装置。[Claims for Utility Model Registration] A rotary drive source 6 is fixed to a driver stand 5 that is movable by an elevating source B, and a mesh drive clutch 8 is connected to its drive shaft 7. A guide tube 2 is provided with a meshing driven clutch 9, the other of which can be forcibly engaged with the lock teeth 11b of the driver body A, on the drive clutch 8, and furthermore, an inclined cam groove 21 is formed in the meshing driven clutch 9.
0 is connected to the driven shaft 15, and this guide cylinder 2
In an automatic screw tightening machine in which a locking pin 23 is embedded in a driver bit 22 in an inclined cam groove 21 of 0 so as to rotate together with a driven shaft 15, the outer cylinder of a meshing drive clutch 8 is fixed to the driver stand 5. An inner cylinder 12 fixed to an outer cylinder 13 is arranged, and a pushing piston 14 that is slidable in the axial direction is inserted between the inner cylinder 12 and the outer cylinder 13, and one end of this pushing piston 14 is engaged. A seizing prevention device characterized in that it is configured to push a driven clutch 9.
