Abstract:
A coupling structure of driving force transmitting members, comprising;a plurality of said driving force transmitting members each having at least one of a concave coupling portion and a convex coupling portion formed on one side in a direction of an axial line thereof,wherein at least one of the plurality of driving force transmitting members further has the other of a concave coupling portion and a convex coupling portion on another side in the direction of the axial line thereof,the plurality of driving force transmitting members being selectively used with the at least one driving force transmitting member having the concave coupling portions and coupled by the concave and convex coupling portions so as to transmit a driving force by rotating about the axial line and to be detachable in the direction of the axial line, anda space setting member having two opposite sides interposed between the respective driving force transmitting members, for setting a space between the respective driving force transmitting members in accordance with a thickness of the space setting member,the space setting member being provided selectively with a concave coupling portion or a convex coupling portion, on both sides in a direction of an axial line thereof,the respective driving force transmitting members and the space setting member being coupled by the concave coupling portions or the convex coupling portions of the driving force transmitting members and the space setting member, so as to transmit a driving force by rotating about the axial line and to be detachable in the axial line direction;the space setting member having concave coupling portions on both sides in a direction of an axial line.
