PROBLEM TO BE SOLVED: To provide a mechanism which can effectively reduce a tooth hammering sound and noise, in a support structure of a rotating shaft of a vehicle which includes a rotor shaft and a drive shaft of an electric motor.SOLUTION: Since at least a part of a cross section of an accommodation groove 80 is inclined to a second rotating axial core C2, inclined faces 80a, 80b are formed at the accommodation groove 80, and an elastic member 72 is accommodated in a state of tightly adhering to the inclined faces 80a, 80b. By this constitution, when thrust forces acting in a thrust direction (axial direction) are transmitted to a second rotor shaft 28 and a reduction shaft 26, the thrust forces act on the inclined faces 80a, 80b, the elastic member 72 is elastically deformed, a collision force is decreased, and noise is reduced.SELECTED DRAWING: Figure 2

    【課題】電動機のロータ軸と駆動軸とを含んで構成される車両の回転軸の支持構造において、歯打ち音や異音を効果的に低減できる機構を提供する。【解決手段】収容溝80の断面の少なくとも一部が第2回転軸心C2に対して傾斜しているため、収容溝80に傾斜面80a、80bが形成され、この傾斜面80a、80bに弾性部材72が密接した状態で収容される。これより、第2ロータ軸28およびリダクション軸26にスラスト方向(軸方向)に作用するスラスト力が伝達されると、そのスラスト力が傾斜面80a、80bに作用し、弾性部材72が弾性変形させられ、衝突力を低減して異音を低減することができる。【選択図】図2
