<p>A motor 2A and a planetary gear type speed reducer 12A are disposed sequentially in this order from an outer side in a width direction of a vehicle, and a motor 2B and a planetary gear type speed reducer 12B are disposed sequentially in this order from an outer side in the width direction, whereby the planetary gear type speed reducers 12A, 12B are disposed between the motors 2A, 2B. At least part of a radially outer edge of a ring gear 24A of the planetary gear type speed reducer 12A or a radially outer edge of a ring gear 24B of the planetary gear type speed reducer 12B is formed smaller than a smaller one of a radially outermost edge portion P1 of the motor 2A and a radially outermost edge portion P2 of the motor 2B. An offset space OS that is recessed further radially than an imaginary line PL that connects the radially outermost edge portion P1 of the motor 2A with the radially outermost edge portion P2 of the motor 2B is provided radially outwards of the ring gear 24A of the planetary gear type speed reducer 12A or the ring gear 24B of the planetary gear type speed reducer 12B, and at least part of a breather chamber 41 of a breather unit 40 and at least part of a strainer accommodation compartment 86 are disposed within the offset space OS. By so doing, it is possible to expand a volumetric capacity room that communicates with an interior of a case.</p> |
