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
