Abstract
To efficiently transmit drive through couplings on one and another sides during forward rotation and reverse rotation. When first and second couplings are brought into engagement with each other and rotated in a forward direction, first and third drive transmission surfaces are brought into contact with each other to be rotated in the forward direction while producing components of force in directions in which the first and second couplings are drawn to each other in the rotational axis direction. When the first and second couplings are brought into engagement with each other and rotated in a reverse direction, second and fourth drive transmission surfaces are brought into contact with each other to be rotated in the reverse direction without producing components of force in directions in which the first and second couplings are separated from each other in the rotational axis direction.
