To provide a wheel drive unit which achieves high practicability.SOLUTION: A wheel drive unit 10 incorporates an electric motor 24 and a speed reducer 26 in a casing 22, is disposed within a rim 20 of a wheel 14, and rotates the wheel. A lubrication oil storage part 100 which stores a lubrication oil in the casing is provided below the electric motor and the speed reducer. A protruding part 104 which protrudes in a direction toward an inner peripheral surface 20a of the rim is provided at a lower part of the lubrication oil storage part. The structure prevents foreign objects having a certain size from being rolled into a space between the lubrication oil storage part and the inner peripheral surface of the rim.SELECTED DRAWING: Figure 2

    【課題】 実用性の高い車輪駆動ユニットを提供する。【解決手段】 ケーシング22内に電動モータ24と減速機26とを内蔵し、ホイール14のリム20内に配置されてそのホイールを回転させる車輪駆動ユニット10において、電動モータおよび減速機よりも下方に、ケーシング内に潤滑油を貯留する潤滑油貯留部100を設け、その潤滑油貯留部の下部に、リムの内周面20aに近づく向きに突出する突出部104を設ける。ある程度の大きさを有する異物が潤滑油貯留部とリムの内周面との間に巻き込まれることが防止される。【選択図】 図2
