To provide a wheel drive device for which a measure against fretting wear can be achieved.SOLUTION: A wheel drive device comprises: a speed reduction mechanism which decelerates rotation transmitted from a driving source; a cylindrical output member 24 to which rotation decelerated by the speed reduction mechanism is transmitted; a base band 26 which is fitted to the output member 24; and a tire 28 which is attached to the base band 26. Tapered surfaces 50, 52 are provided on an outer peripheral surface of the output member 24 and an inner peripheral surface of the base band 26, and the base band 26 is fitted to the output member 24 by interference fitting in the state that the tapered surfaces 50, 52 are brought into contact with each other between the base band itself and the output member 24.SELECTED DRAWING: Figure 2

    【課題】フレッティング摩耗への対策を図れる車輪駆動装置を提供する。【解決手段】駆動源から伝達される回転を減速する減速機構と、減速機構で減速された回転が伝達される筒状の出力部材24と、出力部材24に外嵌されるベースバンド26と、ベースバンド26に取り付けられるタイヤ28と、を備える車輪駆動装置であって、出力部材24の外周面とベースバンド26の内周面とにはテーパ面50、52が設けられ、ベースバンド26は、出力部材24との間で互いのテーパ面50、52を接触させた状態で締まり嵌めにより出力部材24に外嵌される。【選択図】図2
