A spot welding tip detaching apparatus includes a movable plate, an engaging/stopping part, and a holder part. The movable plate has a guide hole through which a shaft set upright in a base plate is inserted with a gap being left between the guide hole and the shaft, rotatable relative to the base plate, and movable along the base plate within a range of the guide hole. The engaging/stopping part stops the movable plate at a predetermined position of the base plate by engagement in an engageable/disengageable manner. The holder part is provided integrally on the movable plate to hold a tip fitted in a spot welding gun. The holder part sandwiches the tip between two members of the holder part. According to movement of the tip along a predetermined route, the holder part rotates the tip, while holding the tip, to detach the tip from the spot welding gun.

A driving force distribution device includes a sub transmission, a friction clutch, a rotary drive member fixed to an output shaft of an actuator, a friction clutch driving cam to change a pressing force of the friction clutch, a shift cam to shift the sub transmission by converting rotary motion of the actuator into linear motion, and a ratchet lever provided so that a shaft line thereof in a normal direction with respect to the outer surface of the rotary drive member is a rotation center. The ratchet lever is disengaged from the shift cam and is rotated when the rotary drive member is rotationally driven to one side from a predetermined position starting at control origin of the shift cam, and the ratchet lever is rotated in conjunction with the shift cam when the rotary drive member is rotationally driven in a direction opposite to the one side.
