PROBLEM TO BE SOLVED: To provide a fitting structure of a rotating shaft which suppress backlash without increasing the number of part items, in the fitting structure for connecting a first rotating body and a second rotating body.SOLUTION: A ring gear R1 and a snap ring 52 are connected to each other by a first protrusion 58 and a first notch 62, and a flange 38 and the snap ring 52 are connected to each other by a second protrusion 60 and a second notch 64. Here, the snap ring 52 is elastically deformed, the ring gear R1 and the flange 38 are energized to a direction in which they oppose each other in a rotation direction by an elastic recovery force of the snap ring 52, and thus, backlash between internal peripheral teeth 50 of the ring gear R1 and external peripheral teeth 48 of the flange 38 can be suppressed. Here, since only the protrusions and the notches are formed at the ring gear R1, the flange 38 and the snap ring 52, an increase of the number of part items can be also prevented.SELECTED DRAWING: Figure 5 |
