Claims

[Claims for Utility Model Registration] A shaft 2, a sleeve 4 disposed on the outer periphery of this shaft via a bearing 3, a flange 5 fitted to the other end of the shaft, and this flange tightened around the shaft. A device for tightening the nut of a shaft-like structure including a nut 6 to be fixed, a positioning step 24 for fixing the flange in a predetermined position of the shaft-like structure in which the nut is temporarily tightened, and the sleeve. a sleeve drive means 25 that engages with the sleeve to rotationally drive the sleeve; a rotational torque sensor 28 that detects the drive torque of the sleeve drive means; a reciprocating drive means 31 that moves the sleeve drive means forward and backward with respect to the sleeve; a nut tightening means 35 that fits into the nut and tightens the nut;
A tightening torque sensor 36 that detects the tightening torque of the nut tightening means, a reciprocating drive means 38 that moves the nut tightening means forward and backward with respect to the nut, and a torque display section 4 that outputs the detection results of both torque sensors.
7. A nut tightening device having a shaft-like structure.
