。[Claims for Utility Model Registration] (1) A resistance welding device comprising a piston rod that moves within a cylinder by the pressurizing force of a fluid, and an electrode member fixed to one end of the piston rod protruding from the cylinder and moving back and forth. In the gun, at least a portion of the piston rod is formed into a tubular shape, and a guide rod is provided in the tubular portion to be slidably fitted to the inner circumferential surface of the piston rod and whose one end is supported by the cylinder, and an electrode member of the piston rod is provided. A piston that is movable within a certain range in the axial direction is attached to one end opposite to the fixed end, and a ring-shaped elastic member is connected between the piston and the guide rod through a tapered surface. Resistance welding characterized in that a ring-shaped pressing member and a current collecting member are provided to fit together, so that when the piston is pressed toward the electrode member, the current collecting member comes into close contact with the piston rod and the guide rod. Gun for use. (2) A cooling water passage is formed in the axial direction within the guide rod, and a cooling pipe having one end opened and fixed to the electrode member mounting portion of the piston rod is slidably attached to the cooling water passage. A resistance welding gun as set forth in claim (1) of the utility model registration claim.
