PROBLEM TO BE SOLVED: To provide a technology for preventing a splashed lubricant from leaking from the inside of a vehicular motor drive device to the outside over a breather structure.SOLUTION: The vehicular motor drive device includes: a breather passage (Q) that is provided in casings (21a, 21r, 22a and 22r) forming an outer shell; an inlet hole (48m) that is provided at an inlet side of the breather passage and connected with an internal space (L) defined by the casings; an outlet hole (67) that is provided at an outlet side of the breather passage and connected with an outer space of the casings; and obstacles (24, 25 and 26) which are erected on an inner wall surface of the breather passage and prevent the lubricant in the internal space from moving straight from the inlet hole to the outlet hole.SELECTED DRAWING: Figure 5

    【課題】潤滑油の飛沫が車両用モータ駆動装置の内部からブリーザ構造を越えて外方へ漏れ出ることを防止する技術を提供する。【解決手段】車両用モータ駆動装置は、外郭をなすケーシング(21a,21r,22a,22r)に設けられるブリーザ通路(Q)と、ブリーザ通路の入口側に設けられてケーシングにより画成される内部空間(L)と接続する入口孔(48m)と、ブリーザ通路の出口側に設けられてケーシングの外方空間と接続する出口孔(67)と、ブリーザ通路の内壁面に立設され、内部空間の潤滑油が入口孔から出口孔に向かって直進することを阻害する障害物(24,25,26)とを備える。【選択図】図5
