Classification: CPC B  F | IPC B  F

Claim 0:
1. A vehicle drive device comprising:
an electric motor,
an input shaft to which power from an engine is input;
a rotor shaft integrally connected to a rotor of the electric motor;
a planetary gear device including a sun gear connected to the rotor shaft so as to be able to transmit power, a carrier connected to the input shaft so as to be able to transmit power, and a ring gear connected to a drive wheel so as to be able to transmit power; and
a case that is a non-rotating member disposed in an engine compartment in which the electric motor, the input shaft, the rotor shaft, and the planetary gear device are housed on a same axis, wherein:
in the vehicle drive device, the input shaft, the rotor shaft, and the sun gear are disposed such that power is transmitted when each of the input shaft and the rotor shaft meshes with the sun gear; and
the vehicle drive device includes
a first ball bearing that supports the input shaft with respect to the case such that the input shaft is rotatable,
a thrust bearing disposed between one end surface of the sun gear in a direction of an axis and the input shaft,
a second ball bearing that is in contact with another end surface of the sun gear in the direction of the axis and that supports the rotor shaft with respect to the case such that the rotor shaft is rotatable, and
a terminal block that is disposed in a space on an opposite side of the electric motor from the planetary gear device and that electrically connects an electric circuit unit for controlling the electric motor and the electric motor.
