PROBLEM TO BE SOLVED: To provide a motor driving apparatus for a vehicle, which is capable of making an outer pin housing light-weight by suppressing an increase in number of components.SOLUTION: This motor driving apparatus for the vehicle includes, in a deceleration part thereof: a deceleration part input shaft (25) extending along an axis (O); a pair of eccentric pars (25a, 25b) formed in the deceleration part input shaft; a pair of curved plates (26a, 26b) rotatably held on the eccentric parts; a plurality of outer pin members (27) engaged with the outer peripheral parts of the curved plates; and an outer pin housing (40) that holds the outer pin members (27) and forms an outer shell of the deceleration part. The outer pin housing (40) comprises a pair of disk--like members (41) facing each other in an axial direction, and a gap between the disk-like members (41) is maintained by butting the outer pin member (27) and the disk-like members (41) to abut on each other in an axial direction.SELECTED DRAWING: Figure 3
【課題】部品点数の増加を抑えて外ピンハウジングを軽量化することのできる車両用モータ駆動装置を提供する。【解決手段】車両用モータ駆動装置の減速部は、軸線(O)に沿って延びる減速部入力軸(25)と、減速部入力軸に形成された一対の偏心部(25a,25b)と、それぞれの偏心部に回転自在に保持される一対の曲線板(26a,26b)と、曲線板の外周部に係合する複数の外ピン部材(27)と、外ピン部材(27)を保持し、減速部の外郭を形成する外ピンハウジング(40)とを含む。外ピンハウジング(40)は、軸線方向に対向する一対の円盤状部材(41)によって構成されており、外ピン部材(27)と各円盤状部材(41)とが軸線方向に突合せ当接することよって、円盤状部材(41)間の間隔が維持される。【選択図】図3
