ABSTRACT:
A rotation-braking damper comprises a housing formed of a cap and a case, a shaft provided at the external end thereof with a toothed wheel and inserted on the internal end thereof into the housing, a disk fastened to the internal end of the inserted shaft, and a lock washer disposed inside the housing as held in contact with the disk. By the lock washer, the shaft in rotation is braked against the cap. The damper of this invention produces a desired braking effect on an opening-closing object such as a lid. The damper can be constructed with a small number of component parts.
