置。[Claims for Utility Model Registration] A coil spring is press-fitted into a cylindrical wall surface of a brake drum body, and only when one of two rotating bodies rotatably attached to the brake drum body rotates, The one pushes in the end of the coil spring against the biasing force of the coil spring, changes the coil diameter of the coil spring, rotates the coil spring away from the cylindrical wall surface, and rotates the other. In the brake lock device, both ends of the coil spring are respectively bent toward the center of the coil, and a locking portion is provided on the one side so that the one side cannot rotate by being locked on the end of the coil spring. At the same time, a hooking portion is formed on the other end of the coil spring to prevent the other from rotating, and when the one of the coil springs rotates, the coil spring is removed from the cylindrical wall surface. In order to separate and rotate, a pressing part capable of pushing the end of the coil spring against the unforced force of the coil spring is formed on the one side, and the end of the coil spring pushed into the pressing part is pressed into the coil. A brake lock device characterized in that a tapered portion is formed on the other side so as to move while abutting in a direction inclined with respect to a center line.
