Claims

[Scope of utility model registration request]

One gun arm and the other gun arm, which is inserted between two legs formed in this arm, are pivoted so as to be movable around a hinge pin that passes through the gun support bracket in common, and is supported at the tip of each arm. In a spot welding can in which a pair of electrode tips are opened and closed by the movement of a gun arm by a pressurized cylinder, one gun arm and gun support bracket are equipped with a bearing into which a hinge pin is rotatably inserted. The other gun arm is a spot welding gun that is fixedly integrated with the hinge pin.
