Description
図1から図8は、本発明の一実施例に係る車両用駆動装置を示す図である。図1から図8において、上下前後左右方向は、車両用駆動装置が搭載された車両の進行する方向を前、後退する方向を後とした場合に、車両の幅方向が左右方向、車両の高さ方向が上下方向である。
図1において、車両1は、左側サイドメンバ2L、右側サイドメンバ2Rおよびサブフレーム3を備えている。
本実施例の駆動装置8は、ライトケース11の側壁部11Eの上部に、ファイナルドリブンギヤ19の上方から側壁部11Eの前端部11fに向かって延び、ファイナルドリブンギヤ19によって掻き上げられたオイルが流れる上側オイル飛散通路部25と下側オイル飛散通路部26とを備えている。
このため、オイルO1が第2の空気導入孔29bを通してブリーザ室27に導入されることを抑制でき、オイルがブリーザ室27から駆動ケース9の外部に漏出することをより効果的に防止できる。
