Kind Code:
A1
Abstract:
[Problem] To provide a rotation position holding mechanism which appropriately biases a locking member while simplifying the shape of the biasing member. [Solution] A rotation position holding mechanism for locking the rotation of an output rotating body when a rotary drive force is not being inputted, the rotation position holding mechanism being characterized in that: a biasing member 145 for biasing a locking member, which locks the rotation of an output rotating body when pressed into the tip-end side of a wedge-shaped space, is equipped with a folded-back section 145a which is a flat spring that is folded back upon itself so as to take on a rounded shape having a larger diameter d3 than the width d1 of an opening 124a, and is housed inside a holding groove 124, and a pair of wing parts 145b obtained by bending the pair of sections, which extend from the folded-back section 145a and pass through the opening 124a, only a single time each so as to separate from one another; and the wing parts 145b bias the locking member.
