ラグ装置。 The plug shaft includes a plug shaft, a work plug attached to the outer surface of the axially intermediate portion of the plug shaft, and a holder coupled to the outer surface of the tip of the plug shaft to hold the work plug at the intermediate portion of the plug shaft. In a plug device for seamless pipe rolling, a locking protrusion is formed on the inner surface of the holder that is connected to the plug shaft, and a locking protrusion is formed on the outer surface of the plug shaft that is connected to the holder. A guide groove that allows the locking protrusion to be guided inward in the axial direction from the tip side of the plug shaft, and a housing groove that is connected to the guide groove and that can accommodate the locking protrusion of the holder. At the same time, a locking rod is inserted into the insertion hole provided axially inward from the tip surface of the center of the plug shaft, and the connecting part between the guide groove and the accommodation groove in the plug shaft and the non-communicating part are inserted. A lock portion integrated with a lock rod is arranged protrudingly within a long hole provided in a region continuously including the lock portion, and the lock portion of the lock rod corresponds to the communication portion between the guide groove and the accommodation groove in the long hole. 1. A plug device for rolling a seamless pipe, characterized in that a resilient member springs the lock rod so that the lock rod is located in a region where the lock rod is located in a region where the lock rod is moved.
