To provide a drive device which enables an electric vehicle to secure a sufficient space to install a battery and other equipment.SOLUTION: An electric vehicle drive device comprises: an in-wheel motor; and a decelerator which transmits rotation of the in-wheel motor to a drive wheel while decelerating a rotation speed of the in-wheel motor. The decelerator has: a sun gear which is driven with the in-wheel motor; a first planetary gear provided with a given number of first teeth arranged so as to be engaged with the sun gear; a fixed ring gear which is engaged with the first planetary gear and arranged not to be rotatable; a second planetary gear which is engaged with the first planetary gear and provided with a given number of second teeth less than the first teeth; a movable ring gear which is engaged with the second planetary gear and arranged to be rotatable; and a transmission member to transmit rotation of the movable ring gear to the drive wheel.SELECTED DRAWING: Figure 2

    【課題】バッテリなどを設置するための十分なスペースを電動車両に確保することが可能な駆動装置を提供する。【解決手段】電動車両の駆動装置は、インホイールモータと、このインホイールモータの回転速度を減速して電動車両の駆動輪に伝達する減速機と、を備え、減速機は、インホイールモータによって駆動される太陽歯車と、太陽歯車と噛み合わせて配置された第1歯数を有する第1遊星歯車と、第1遊星歯車と噛み合わされて回転不能に配置された固定リングギヤと、第1遊星歯車に結合された、第1歯数よりも少ない第2歯数を有する第2遊星歯車と、第2遊星歯車と噛み合わされて回転可能に配置された可動リングギヤと、可動リングギヤの回転を駆動輪に伝達するための伝達部材と、を有する。【選択図】 図2
