PROBLEM TO BE SOLVED: To provide a brake device capable of materializing unidirectionality without regulating a rotating direction of a rotor.SOLUTION: A brake device is equipped with a housing 10, a rotor 20 provided in the housing 10, a brake shoe 30 provided between the rotor 20 and the housing 10, a first projecting portion 40 which moves with the brake shoe 30, and a second projecting portion 50 which moves with rotations of the rotor 20. The first projecting portion 40 climbs up on the second projecting portion 50 only when the rotor 20 normally rotates, thereby generating a friction larger than a friction between the brake shoe 30 and the housing 10 which can be generated when the rotor 20 reversely rotates, between the brake shoe 30 and the housing 10. |
