The drive power connecting/disconnecting device includes a second shaft disposed coaxially to a first shaft so as to transmit drive power to a wheel axle, a connection/disconnection member which moves a second rotational body along an axial direction with respect to a first rotational body, and which is capable of moving in the axial direction so as to make or break engagement between the first shaft and the second shaft, a supporting member, a shaft cover which covers at least the periphery of the second rotational body, a first pivotally supporting portion which is disposed between the first shaft and the second shaft so as to axially support one end of the second shaft; and a second pivotally supporting portion which is disposed inside the shaft cover so as to axially support the other end of the second shaft.

Drive power connecting/disconnecting device

Three switching units and three smoothing capacitors are disposed in parallel with each other in the x-direction on a substrate having an x-y plane. A surface conductor and a rear conductor, which include bases extending in the x-direction and three branches extending in the y-direction therefrom, are laminated to form a feeding bus bar 8 for connecting the respective units and the respective capacitors. The three branches have the same pattern and are distributed in the x-direction at the same pitch as the x-direction arrangement of the units 2-4. The connection patterns of the respective units and the respective branches are the same for the three pairs.

Switching assembly

A power train device is provided with an electric motor including a cylindrical stator wound with electric oils and a cylindrical rotor which is disposed radially inwardly of the stator and rotated by energization of the electric coils. A reduction gear mechanism is provided for reducing the number of rotations of the rotor, and a differential gear mechanism is provided for supplying rotation power from the output of the reduction gear mechanism to a pair of drive shafts connected to each wheel and for absorbing a differential between the wheels. A cover covers the electric motor, the reduction gear mechanism and the differential gear mechanism, and the reduction gear mechanism is mounted radially inwardly of the cylindrical rotor.
