A first rotational bodyand a second rotational bodyarranged downstream of a driven rotational bodyin a drive train that transmits a driving force from a driving rotational bodyto a driven memberare included. The first rotational bodyrotates in synchronization with the driven rotational body. The second rotational bodyis rotated by the first rotational bodyand rotates the driven member. The first rotational bodyrotates without rotating the second rotational bodywhen the driven rotational bodyrotates by an elastic force of an elastic member
