ことを特徴とする過負荷防止装置。 A frame body formed with an inclined surface that opens symmetrically on one side in the axial direction, a load rod that is slidably inserted in the frame body in the axial direction and has a protrusion that protrudes laterally in the middle part, and an outer surface. a movable member having an inclined surface in close contact with the inclined surface of the frame and arranged to sandwich the load rod; and pressing the movable member in the axial direction so that the inclined surface comes in close contact with the inclined surface of the frame. The spring has strength to withstand the load during the test, and the surface of the movable member facing the load rod is formed with a concave portion having an outwardly opening inclined surface. When the member is pressed to the maximum extent against the frame, the protrusion of the load rod engages with the recess, mechanically integrating the load rod and the frame via the movable member, resulting in an excessive load. The present invention is characterized in that the movable member is moved along the inclined surface of the frame body against a spring, and the protrusion deviates from the recess so that the load rod freely moves independently of the frame body. Overload prevention device.
