PROBLEM TO BE SOLVED: To provide an attachment structure of a rear wheel drive unit of a vehicle which can surely obtain a downward turn by the rear wheel drive unit at a collision of the vehicle, and can alleviate an impact to an occupant.SOLUTION: An attachment structure of a rear wheel drive unit of a vehicle comprises: a differential device 1 arranged at a rear part of a vehicle body; a propeller shaft 5 which transmits a drive force of a power unit 2 arranged at a front part of the vehicle body to the differential device 1, and extends to a fore-and-aft direction of the vehicle body; a mount connecting part 51 which is arranged while being offset to a vehicle width direction and a vertical direction with respect to an axial core C of the propeller shaft 5 at a rear end part of the differential device 1; a bolt member 52 extending rearward from a rear end part of the mount connecting part 51; a mount member 53 attached to a rear end side portion of the bolt member 52 in a substantially-coaxial state; and an attachment bracket 54 for fixing the mount member 53 to an auxiliary member 16. An extension part 54c which is overlapped with the mount connecting part 51 is arranged at an outside portion of the attachment bracket 54 in the vehicle width direction.

    【課題】車両前突時における後輪駆動装置による下方回動を確実に実現でき、乗員への衝撃を軽減できる車両の後輪駆動装置取付構造を提供する。【解決手段】車体後部に設けられた差動装置1と、車体前部に設けられたパワーユニット2の駆動力を差動装置1に伝達する車体前後方向に延びるプロペラシャフト5と、差動装置1の後端部にプロペラシャフト5の軸心Cに対して車幅方向と上下方向にオフセットさせて設けられたマウント連結部51と、マウント連結部51の後端部から後方へ延びるボルト部材52と、ボルト部材52の後端側部分に略同軸状態で取り付けられたマウント部材53と、マウント部材53を補助メンバ16に固定する取付ブラケット54とを備え、取付ブラケット54の車幅方向外側部分にマウント連結部51と重なり合う延長部54cを設けた。【選択図】 図4
