とを特徴とする電装用可動駒のストツパ装置。 A movable piece whose rotation around the axis is regulated is screwed onto a feed screw carved into an output shaft that rotates, so that the movable piece is moved in the axial direction based on the rotation of the output shaft. and forming a small diameter part in which a screw into which a nut is screwed is carved in the tip of the output shaft, and when the movable piece reaches the movement limit on the output shaft tip side, in the small diameter part, A stopper supported by the threaded nut is provided to receive a damper provided on the movable piece in a press-like manner to restrict movement of the movable piece beyond the movement limit, and the small diameter portion includes: A washer is disposed on the damper receiving surface side of the stopper and coated with a resin material to reduce sliding resistance on the sliding surface facing the stopper, and is freely rotatable, and the washer is coated with lubricating oil. For electrical equipment, characterized in that a passage hole is bored so that lubricating oil transmitted through the output shaft can enter between the opposing sliding surfaces of the washer and the stopper through the passage hole. Stopper device for movable pieces.
