Claims

[Scope of utility model registration request]

The damper is a damper that provides resistance to the spring force that operates a load member such as a tee housing part, and is provided with an input part to which the spring force is applied as a rotational force at one end of the sun axle, and the sun axle is connected to the inner circumferential surface of the damper. A planetary gear unit consisting of the sun gear, a plurality of planetary gears, and the above-mentioned internal gear is mounted around the sun axle in the axial direction. Arranged in multiple stages,
Each planetary gear of the first-stage planetary gear unit is pivotally supported to the input part, each planetary gear of the second-stage and subsequent stages is pivotally supported to the sun gear of the unit in the previous stage, and the sun gear of the final stage is A disc-shaped part is connected to the gear, and the disc-shaped part is provided with a plurality of recessed holes opening on the outer circumferential side at regular intervals in the circumferential direction. The damper is equipped with a contact piece that protrudes in the outer circumferential direction due to the centrifugal force caused by the centrifugal force and slides into contact with the inner circumferential surface of the damper case to provide rotational resistance to the final stage sun gear.
