Abstract:
An electric vehicle drive device includes: a first motor; a second motor, and a transmission mechanism coupled to the first motor and the second motor and capable of switching a reduction ratio. The transmission mechanism includes a sun gear shaft coupled to the first motor. The first motor includes: a first stator core, a first rotor core disposed radially outward of the first stator core, and a first rotor holding member that couples the first rotor core and the sun gear shaft.

Claim (Index 8):
The electric vehicle drive device according to  claim 7 , comprising a case that supports the first motor, the second motor, and the transmission mechanism, wherein\n the first outer member includes an outer tube portion, an inner tube portion, a coupling portion, and a rib, the outer tube portion, the inner tube portion, the coupling portion, and the rib are integrated, the outer tube portion is a cylindrical member, an inner peripheral surface of the outer tube portion is in contact with an outer peripheral surface of the first rotor core, an outer peripheral surface of the outer tube portion is opposed to an inner peripheral surface of the case, the inner tube portion is a cylindrical member disposed radially inward of the outer tube portion, and is in contact with the first inner member, the coupling portion couples one end of the outer tube portion and one end of the inner tube portion, a radially outer end portion of the coupling portion is located radially outward of the first stator core, a radially inner end portion of the coupling portion is located radially inward of the first stator core, the outer tube portion is located radially outward of the first stator core, the inner tube portion is located radially inward of the first stator core, and the rib is an annular member protruding from the coupling portion in an axial direction.
