This welding gun (10A) is provided with a driving-force transmission mechanism (18) which converts linear displacement of an output unit of a driving unit (14) into rotational displacement of a clamping arm (16). The driving-force transmission mechanism (18) is provided with: an inclined part (94) which is integrally displaced with the linear displacement of the output unit, and which is inclined with respect to the displacement direction of the output unit; and a part (96) to be pressed which is pressed by the inclined part (94). The clamping arm (16) rotates in accordance with movement of the part (96) to be pressed which is pressed by the displaced inclined part (94), and generates clamping force. |
