<P>PROBLEM TO BE SOLVED: To provide a driving force transmitting member which can be miniaturized while it can be assembled inexpesively through a single operation. <P>SOLUTION: The driving force transmitting member is held rotatably in the supporting shaft 34 at the opposed state by a final gear 32 and a cooperation gear, and a plurality of heavy-walled bosses 39 are projected in the diametric direction so as to encircle a rotational center in the cooperation gear, and a plurality of ribs 37 which are elastically contacted along the circumference as a surface to be elastically contacted 39a at a surface to be lengthened in the radial direction of the boss 39 in the final gear 32 are projected and, while inserting the peripheral wall 36 provided in the final gear 32 among a plurality of bosses 39, the cooperation gear is coaxially fitted and held in the final gear 32 by elastically contacting the rib 37 to the elastically contact with the surface 39a. <P>COPYRIGHT: (C)2008,JPO&INPIT |
