However, since the air motor has a small output, it is difficult to directly rotate and screw together a large female or male threaded member. Therefore, in the present invention, the female threaded member or the male threaded member is idled before screwing. Since the female threaded member or the male threaded member has a large mass, a large torque is generated due to the inertia of the member during idle rotation. A large torque based on such inertia rotates the female threaded member or the male threaded member, thereby threadingly connecting the female threaded member and the male threaded member.
