To reduce dimensions in a longitudinal direction and a vertical direction around a motor shaft and gear shaft of a mobile body drive unit when the motor shaft and gear shaft are arranged so as to extend in a front-and-back direction of a mobile body in the mobile body drive unit.SOLUTION: A mobile body drive unit 20 includes: an electric motor 32 which is arranged in an inside of a case and has a motor shaft extending in a first direction; a gear shaft 90 which is arranged in the inside of the case along with a motor shaft so as to extend in the first direction, and has a bevel gear; an intermediate gear mechanism 94 which transmits power from the motor shaft to the gear shaft; and a differential gear device 98 which is arranged in the inside of the case, has a ring gear meshed with the bevel gear, and transmits power from the gear shaft 90 to two output shafts 110 extending in a second direction. The motor shaft and gear shaft are arranged in different positions in both of the second direction and a third direction orthogonal to both of the first direction and the second direction.SELECTED DRAWING: Figure 6

    【課題】移動体駆動ユニットにおいて、モータ軸及びギア軸を移動体の前後方向に延びるように配置した場合に、移動体駆動ユニットにおけるモータ軸及びギア軸の周囲での左右方向及び上下方向の寸法を小さくすることである。【解決手段】移動体駆動ユニット20は、ケースの内側に配置され、第1方向に延びるモータ軸を有する電動モータ32と、ケースの内側に、第1方向に延びるようにモータ軸と並んで配置されベベルギアが形成されたギア軸90と、モータ軸からギア軸に動力を伝達する中間ギア機構94と、ケースの内側に配置され、ベベルギアに噛み合うリングギアを有し、第2方向に延びる2つの出力軸110に、ギア軸90から動力を伝達する差動ギア装置98とを含む。モータ軸とギア軸とは、第1方向及び第2方向の両方に直交する第3方向と、第2方向との両方について異なる位置に配置される。【選択図】図6
