PROBLEM TO BE SOLVED: To provide a wheel driving device capable of preventing vibration of an outer pin housing 50 of a cycloid type reduction gear 20 from being transmitted to a vehicle body, and easy to coaxially arrange the floatingly-supported reduction gear 20, a motor part 10 and a wheel hub bearing part 30.SOLUTION: An outer pin housing 50 held in a floating state on a casing 11b of a reduction gear 20 is provided with an elastic metal plate 60 for elastically supporting the same in the axial direction relative to an inner wall of the casing 11b of the reduction gear 20. A casing side plate 60c of the elastic metal plate 60 and the inner wall surface of the casing 11b are coupled via a face joint by friction force or a flexible coupling, so that the reduction gear 20 is aligningly arranged on the same axis with a motor part 10 and a wheel hub bearing part 30.SELECTED DRAWING: Figure 5

    【課題】 サイクロイド式の減速機20の外ピンハウジング50の振動が、車体に伝達されるのを防止することができ、フローティング支持された減速機20と、モータ部10と、車輪ハブ軸受部30を同一軸心上に配置しやすい車輪駆動装置を提供する。【解決手段】 減速機20のケーシング11bにフローティング状態で保持された外ピンハウジング50に、減速機20のケーシング11bの内壁に対して軸方向に弾性的に支持する弾性金属板60を設け、この弾性金属板60のケーシング側プレート60cと、ケーシング11bの内壁面との間を摩擦力による面接合、あるいはフレキシブルカップリングを介して締結することにより、減速機20が、モータ部10、車輪ハブ軸受部30に対して同一軸心上に調心配置されるようにした。【選択図】 図5
