するスプリングブレーキ装置。[Claims for Utility Model Registration] An input-side rotating body and an output-side rotating body are rotatably attached to a brake drum body, and two coil springs are fitted in pressure contact with a cylindrical wall surface of the brake drum body. A spring brake device configured to transmit rotational force only from the input side rotary body to the output side rotary body, wherein the claw portion of the output side rotary body is provided in a notch cut in the input side rotary body. is inserted, the input side rotating body rotates in either direction, and by pushing one end of one of the two coil springs, the one coil spring rotates while changing the coil diameter, Furthermore, when the input-side rotary body rotates, the notch pushes in one end of the other coil spring and pushes in the claw part, thereby rotating the other coil spring and the output-side rotary body, A spring for preventing backlash is housed in the brake drum body, and fitting portions are formed on the input side rotating body to be elastically inserted into both ends of the spring for preventing backlash, and other than the one coil spring. The play stopper is attached to the other end of the one coil spring and one end of the other coil spring so that the end of the coil spring and one end of the other coil spring elastically sandwich the claw portion of the output rotating body. A spring brake device characterized in that both ends of a spring are pressed together.
