Claims

[Scope of utility model registration request]

A rotary shaft body is rotatably supported on the cylindrical frame at its center position, and a cylindrical sliding body that is slidable in the circumferential direction is disposed on the inner peripheral surface of the cylindrical frame, and the rotary shaft body is A rotating disc body is rotatably fitted onto the outside, one end of the claw body is pivotally supported at an eccentric position of the rotating disc body, and the other end of the claw body is biased toward the center of the rotating disc body. a first spring body is provided on the inner circumferential surface of the sliding body, an engaging protrusion that can be freely engaged with and detached from the claw portion of the claw body, and a through hole formed in the cylindrical frame is provided on the outer circumferential surface of the sliding body. An actuating piece is provided that protrudes further outward, a brake lining is attached to the side of the rotating disc body, and a brake plate is slidably moved in the axial direction at a position corresponding to the brake lining on the rotating shaft body. a second spring body for biasing the brake plate against the brake lining, and a means for detecting sliding of the sliding body actuated by the actuation piece on the cylindrical frame; The means includes a rod-shaped body that is slidably held in a guide cylinder attached to a cylindrical frame substantially along the moving direction of the actuating piece, and a third member that presses and biases one end of the rod-shaped body toward the actuating side. It is characterized by being composed of a spring body, a stopper that is screwed onto a threaded portion on the other end of the rod-like body to restrict the amount of protrusion on one side of the rod-like body, and a limit switch that is interlocked with the other end of the rod-like body. Governor brake.
