A miniaturized vehicular drive apparatus is provided with a reduced size in an axial direction without increasing the number of parallel shafts. A first electric motor M1 and a power distributing mechanism (differential portion) 16 are disposed on a first axis CL1, forming a rotational axis of an input rotary member 14, in series starting therefrom and an automatic transmission (transmission portion) 20 is disposed on a second axis CL2 parallel to the first axis CL1. A drive linkage 23 is provided between a power transmitting member 18, acting as a rotary member placed on the first axis CL1 at an end portion thereof in opposition to the input rotary member 14, i.e., in opposition to an engine 8, and a first intermediate shaft (rotary member) 40, disposed on the second axis CL2 at an end portion thereof in opposition to the input rotary member 14, for power transmitting capability. Thus, a power transmitting path is formed in a C-shape, i.e., a U-shape with a reduction in size of the axial direction, enabling the miniaturization to provide a simplified structure without increasing the number of parallel shafts.
