Abstract
A gear center-distance maintaining mechanism includes a first support body that rotatably supports a first gear to be rotated by driving force from a driving unit, a second support body that rotatably supports a second gear to be meshed with the first gear so as to transmit rotational force from the first gear to a rotating body, the second support body being movable relative to the first support body in a direction such that the second gear moves away from the first gear, an arc-shaped face provided in the second support body and centered on an axis of the second gear, and a restricting portion provided in the first support body and shaped like an arc centered on an axis of the first gear, the restricting portion restricting the movement of the second support body relative to the first support body by contact with the arc-shaped face.
