Zusammenfassung:	PROBLEM TO BE SOLVED: To easily separate a screw member from a rotary shaft in screw disassembling work. SOLUTION: A small diameter female spiral 18 is provided in the front end of a rotary shaft 5 and a large diameter female spiral 19 having an inner diameter larger than the diameter of the small diameter female spiral 18 is provided in the closed end 8 of a screw member 6 at the position corresponding to the small diameter female spiral 18 in the fitting state of the rotary shaft 5 and the screw member 6 and a fixing screw 9 having the small diameter male spiral 21 capable of being threaded with the small diameter female spiral 18 is screwed in the large diameter female spiral 19 of the closed end 8 of the screw member from the outside in the fitting state of the rotary shaft 5 and the screw member 6 to assemble a screw 10 and, after the fixing screw 9 is detached, a release screw 22 is screwed in the large diameter female spiral 19 to relatively separate the rotary shaft 15 from the screw member 6 to disassemble the screw 10.
