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.
Claims8
A braking device comprising:
- a housing;
- a rotor provided inside the housing;
- a brake shoe provided between the rotor and the housing;
- a first protruding part configured to move together with the brake shoe;
- and
- a second protruding part configured to move in association with rotation of the rotor,
- wherein the first protruding part is pushed up by a moving of the second protruding part only when the rotor is in normal rotation such that friction larger than friction occurring between the brake shoe and the housing when the rotor is in reverse rotation, occurs between the brake shoe and the housing.
Dependencies are inferred from the claim text.
