To suppress a backflow of oil from an oil storage part to a guide oil path at the abrupt brake of a vehicle while securing the circulation of the oil in the guide oil path at normal traveling, in a drive unit for a vehicle in which the guide oil path for guiding the oil to the oil storage part is opened at a wall face extending in a vertical direction of a case at the oil storage part side.SOLUTION: A drive unit for a vehicle comprises: an oil storage part arranged at a rear side of a vehicle with respect to a case, and storing oil; a guide oil path for guiding oil supplied from the oil storage part in order to cool a rotating electric machine to the oil storage part, and opened at a wall face extending in a vertical direction of the case at the oil storage part side; and a block member suspended by a support part arranged in a position apart from the wall face to a rear side of a vehicle so as to be turnable, releasing the guide oil path in an attachment state, turning around the support part ahead of the vehicle by an action of a force in a vehicle frontward posture, and capable of blocking the guide oil path.SELECTED DRAWING: Figure 2 【課題】油を油貯留部に案内する案内油路がケースの上下方向に延在する壁面で油貯留部側に開口する車両用駆動装置において、通常走行時に案内油路の油の流通を確保しつつ車両の急制動時に油貯留部から案内油路への油の逆流を抑制する。【解決手段】ケースに対して車両後方に設けられて油を貯留する油貯留部と、油貯留部から回転電機を冷却するために供給された油を油貯留部に案内すると共にケースの上下方向に延在する壁面で油貯留部側に開口する案内油路と、壁面から車両後方に離間した位置に配置された支持部により回動自在に吊り下げられ、取付状態で案内油路を開放すると共に車両前向きの力の作用により支持部周りに車両前方に回動して案内油路を閉鎖可能な閉鎖部材とを備える。【選択図】図２
