Claims

[Scope of utility model registration request]

A plurality of studs are fixed perpendicularly to a bearing bracket, an electromagnet is attached to the studs so as to be movable in the axial direction, and the studs are located between the electromagnets and the bearing bracket and can be integrated with the rotating shaft. A brake disk is provided to be movable in the axial direction, and a brake shoe is provided to be movable in the axial direction between the brake disk and the electromagnet and is attracted by the electromagnet when the electromagnet is energized. a compression spring that constantly presses the brake shoe toward the bearing bracket; a weak compression spring that presses the electromagnet toward the brake shoe; a plurality of slopes provided on a part of the outer periphery of the electromagnet; a plurality of adjusting parts located between the slope and the bearing bracket; having a fulcrum on the bearing bracket; one arm touching the brake disc side of the brake shoe; and the other arm rotatably connected to the adjusting fitting; In a brake consisting of a plurality of levers and a compression spring disposed between the arm on the brake shoe side of the lever and the bearing bracket, the tangent of the ratio of the length of the arm of the lever is the value of the slope. The brake is characterized in that the value of the gradient is made smaller than the friction angle of the gradient part, and the direction of the gradient is set in a direction in which the adjusting part and the gradient part of the electromagnet separate when the brake shoe is pressed by the lever arm.
