Claims

[Scope of utility model registration request]

A movable member having a substantially central portion of the arm member supported on a support by a horizontal axis orthogonal to the arm member, a counterweight provided at one end of the arm member, and a nut runner suspended from the other end of the arm member. axially movably engaged;
A stopper for regulating the amount of movement of the moving member is protruded from the arm member at a front and back position in the moving direction of the moving member,
The bolt/nut tightening device is further characterized in that the cylinder rod is disposed on the arm member's movable member coupling side of the support column so that the front end surface of the cylinder rod is directed toward the lower surface of the arm member's movable member retaining side.
