<P>PROBLEM TO BE SOLVED: To provide low cost and high image quality color image forming apparatus. <P>SOLUTION: A driving shaft 2 is retained to two pieces of side plates 3 and 4 through a bearing 5. A driving motor 7 is installed on one side plate 4 through a bracket 6. The driving motor 7 is aligned and connected to a driving shaft 2 at a boss part 7a. The boss part 7a of the driving motor 7 has a solid hole 7b opened in one part and a screw hole 7c opened in another part. Furthermore, a driving shaft 2 has a through hole 2a opened. A screw 8 is screwed into a screw hole 7c by passing through the through hole 2a from the hole 7b side. In addition, a slit 7d is cut in the boss part 7a, the boss part 7a is compressed by a head of the screw 8 and the screw hole 7c when a tightening torque is applied to the screw 8, inside diameter of the boss part 7a which is easily deformed is made narrower by the slit 7d and the driving shaft 2 and the boss part 7a are stuck by pressure and integrated. In this state a different part does not intervene between the driving shaft 2 and the driving motor 7, so that needless eccecntricity or rattling are not produced. <P>COPYRIGHT: (C)2007,JPO&INPIT |
