Claims

[Scope of Claim for Utility Model Registration] A nut tightening device in which a nut runner having a socket at its lower end and vertically slidable is disposed above a tightening bolt fixed upward, It is installed inside the nut runner so that it can freely slide up and down in line with the axis of the nut runner,
A rod member is pressed by a spring member and always protrudes from the lower end of the nut runner, and the rod member is supported so as to be able to swing freely around one point, and the end portion of the rod member swings downward by the spring member to be positioned. It has a conveyance path for conveying the nut to the end, and the upper surface of the end is inclined downward toward the rod member, and the rod member can pass through the lower nut and move further to the lower tightening bolt. a nut supplying device having a direction groove formed on the end face of the end portion; and a nut supplying device provided in the conveyance path at the end of the nut supplying device in a normally closed state by a spring member, so that the nut runner is lowered and the nut runner is An automatic nut supply and tightening device comprising a stopper pawl whose lower end presses the top surface of the end of the nut supply device and opens when the nut supply device swings.
