Coupling structure of driving force transmitting members

摘要

A coupling structure of driving force transmitting members, comprises gear members (101-104) and maybe spacers, each provided with concave coupling portions (101a-104a) and/or convex coupling portions (101b-104b) on one and/or other of their axial faces. The respective convex coupling portions (101b-104b) are fitted into the respective concave coupling portions (101a-104a), whereby the gear members (101-104) are coupled to integrally rotate. Thus, it is possible to selectively combine a plurality of gear members (101-104) and construct many kinds of complex-type gear members (500).
