Abstract
A slide disk that is displaceable when the slide disk is bent toward a base section of a frame is provided at a main shaft, and a friction surface that can contact a pressing portion of the slide disk is provided at the base section. The pressing portion of the slide disk normally presses the friction surface to cause the pressing portion of the slide disk to normally press the friction surface, and hence a pressing force for applying to the main shaft a rotational resistance that permits rotation of the main shaft normally acts on the main shaft. Accordingly, even if the position of the center of gravity of a member to be rotated is deviated from a rotation axis of the main shaft, the rotational resistance can be applied to the main shaft.
