ABSTRACT:
A rotation damper comprises a base member, a gear wheel rotatably mounted on the base member via a damper, a spiral spring having one end attached to a cap member and the other end attached to the gear wheel and adapted to be wound up with the rotation of the gear wheel, and a locking member for locking the spiral spring in or releasing it from the wound-up state. When the gear wheel is rotated to the neighborhood of a limit position against the spring force of the spiral spring, the spiral spring is locked in the wound-up state. The spiral spring is released from the wound-up state by further rotating the gear wheel. The rotation damper is applicable to a cassette holder of a cassette tape recorder, for instance, and permits the holder to be opened and closed under braking force while eliminating the need for a separate holder locking mechanism.
