To maintain versatility of an in-wheel motor driving device and achieve increase of a size of a motor of the in-wheel motor driving device at low costs.SOLUTION: An in-wheel motor driving device 21 includes: a motor part A; a speed reducer part B; a wheel bearing part C; and an oil pump D for supplying an oil to the motor part A or the speed reducer part B. The speed reducer part B has: an input shaft 34 to which a rotational driving force generated by the motor part A is input; an output shaft 36 which is disposed parallel to the input shaft 34 and from which the rotational driving force is output; and an input gear 30 and an output gear 33 respectively provided at the input shaft 34 and the output shaft 36. The oil pump D is provided closer to the outboard side than the output gear 33 of the output shaft 36.SELECTED DRAWING: Figure 1
【課題】インホイールモータ駆動装置の汎用性を保ちつつも、当該インホイールモータ駆動装置のモータの大型化を低コストに図る。【解決手段】インホイールモータ駆動装置21は、モータ部Aと、減速機部Bと、車輪用軸受部Cと、モータ部A又は減速機部Bに向けてオイルを供給するためのオイルポンプDとを備える。減速機部Bは、モータ部Aによる回転駆動力が入力される入力軸34と、入力軸34に対して平行に配置され回転駆動力が出力される出力軸36と、それぞれ入力軸34と出力軸36とに設けられる入力歯車30と出力歯車33とを有する。出力軸36の出力歯車33よりもアウトボード側に、オイルポンプDが設けられる。【選択図】図1
