PROBLEM TO BE SOLVED: To provide a wheel driving apparatus in which countermeasure against leakage of a lubrication agent may be effectively achieved.SOLUTION: There is provided a wheel driving apparatus comprising a deceleration mechanism 20 decelerating rotation transmitted from a drive source; a rotator 22 to which rotation decelerated by the deceleration mechanism 20 is transmitted and to which a wheel is integrated; fixing members 24-A, 24-B rotatably supporting the rotator 22; an oil seal 26 which is arranged between the rotator 22 and the fixing members 24-A, 24-B and seals a space where deceleration mechanism 20 is accommodated; and lubrication agents 60-A, 60-B stored in a storage space 28 sealed with the oil seal 26. The lubrication agents 60-A, 60-B comprise at least 2 types of the lubrication agents 60-A, 60-B having different worked penetrations. A volume of the stored lubrication agents 60-A, 60-B is 35% or less of a volume of the storage space 28.SELECTED DRAWING: Figure 3

    【課題】潤滑剤の漏れ対策を効果的に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20と、減速機構20で減速された回転が伝達され、車輪が一体化されている回転体22と、回転体22を回転自在に支持する固定部材24−A、24−Bと、回転体22と固定部材24−A、24−Bの間に配置され、減速機構20が収納される空間を封止するオイルシール26と、オイルシール26により封止される封入空間28に封入される潤滑剤60−A、60−Bと、を備える車輪駆動装置であって、潤滑剤60−A、60−Bは、混和ちょう度の異なる少なくとも2種類の潤滑剤60−A、60−Bを含み、潤滑剤60−A、60−Bの封入量は、封入空間28の容積の35%以下である。【選択図】図3
