摘要： A welding gun driving device is provided with an electric motor, a feed screw mechanism, and a pressure rod axially moved forward and backward via the feed screw mechanism by the electric motor. A rotor of the electric motor is formed into a hollow shape through which the pressure rod is insertable. The feed screw mechanism is provided with a screw shaft fixed to the rotor concentrically with the rotor, and a nut portion screwed to the screw shaft. The pressure rod is provided with the nut portion and a hollow rod portion extending toward the axial front from the nut portion. The rotor is provided, at its inner peripheral face, with a guide portion through which the pressure rod is inserted and supported so as to be relatively rotatable and axially slidable.

摘要： A welding gun is provided in which moisture does not penetrate inside of a motor housing due to preventing the inside of the motor housing from becoming negative pressure. The welding gun includes a feed screw mechanism (40) that is coupled to a servo motor (10) and has a hollow rod (43) that reciprocally moves in a predetermined direction by way of torque applied by the servo motor (10), and a moveable electrode tip (62) that is connected to a leading end portion of the hollow rod (43) and opens and closes relative to a fixed electrode tip (61) according to the reciprocal movement of the hollow rod (43). The servo motor 10 has a motor housing (20) in which a motor housing hollow part (25) accommodating a portion of the hollow rod (43) to be reciprocally moveable is formed. A vent (21b) that ventilates the motor housing hollow part (25) with ambient air is formed in the motor housing (20).
