To provide a vehicular electric drive device which enables an axial dimension to be reduced to be a small dimension.SOLUTION: A transmission 1 changes a speed of rotation transmitted from the side of a rotary electric machine MG and includes: a first transmission shaft TS1 disposed along a direction orthogonal to a pair of axles DS when viewed along a vertical direction V; and a first transmission gear TG1 disposed coaxially with the first transmission shaft TS1. A brake mechanism 3 includes: a rotary member 31 which is connected with the first transmission shaft TS1 so as to rotate integrally therewith; a restriction member 32 which restricts rotation of the rotary member 31; and a driving unit 33 which drives the restriction member 32. The first transmission shaft TS1 is disposed at a first side L1 in an axial direction relative to a differential gear mechanism 2. The rotary member 31 is disposed at the first side L1 in the axial direction relative to the first transmission gear TG1. The driving unit 33 protrudes to a second side L2 in the axial direction relative to the rotary member 31 and is arranged so as to overlap with the transmission 1 when viewed along a radial direction R of the first transmission shaft TS1.SELECTED DRAWING: Figure 1

    【課題】軸方向の寸法を小さく抑えることができる車両用電動駆動装置を提供する。【解決手段】回転電機MGの側から伝達される回転を変速する変速機1は、上下方向Vに沿う上下方向視で一対の車軸DSに対して直交する方向に沿って配置された第1変速軸TS1と、当該第1変速軸TS1と同軸に配置された第1変速ギヤTG1と、を備え、ブレーキ機構3は、第1変速軸TS1と一体的に回転するように連結された回転部材31と、当該回転部材31の回転を規制する規制部材32と、当該規制部材32を駆動する駆動ユニット33と、を備え、第1変速軸TS1は、差動歯車機構2に対して軸方向第1側L1に配置され、回転部材31は、第1変速ギヤTG1に対して軸方向第1側L1に配置され、駆動ユニット33は、回転部材31に対して軸方向第2側L2に突出すると共に、第1変速軸TS1の径方向Rに沿う径方向視で、変速機1と重複するように配置されている。【選択図】図1
