Abstract
To provide a braking device that achieves unidirectionality without limiting the direction of rotation of a rotor. The present invention is characterized by being equipped with a housing (10), a rotor (20) provided inside the housing (10), brake shoes (30) provided between the rotor (20) and the housing (10), first protruding parts (40) that move together with the brake shoes (30), and second protruding parts (50) that move in conjunction with the rotation of the rotor (20), with the first protruding parts (40) riding up on the second protruding parts only when the rotor (20) rotates in the normal direction, and thereby generating greater friction between the brake shoes (30) and the housing (10) than the friction that can be generated between the brake shoes (30) and the housing (10) when the rotor (20) rotates in the reverse direction.
