1. A vehicle drive device comprising:
a rotation electric machine;
a power transmission mechanism configured to transmit power based on a rotational torque generated by the rotation electric machine to a wheel;
a drive device configured to drive the rotation electric machine;
an accommodating member in which a first accommodating chamber which accommodates the rotation electric machine, a second accommodating chamber which accommodates the power transmission mechanism, and a third accommodating chamber which accommodates the drive device are internally formed;
a rotation angle sensor provided at an end portion of the rotation electric machine at a second accommodating chamber side in an axial direction in the first accommodating chamber and configured to acquire rotation angle information of the rotation electric machine; and
a first interconnect electrically coupling the rotation angle sensor and the drive device, wherein
in the accommodating member, a first partition wall portion which partitions the first accommodating chamber and the second accommodating chamber in the axial direction and a second partition wall portion which partitions the first accommodating chamber and the second accommodating chamber from the third accommodating chamber in a radial direction are formed,
the first interconnect is routed so as to reach an inside of the second accommodating chamber from an inside of the first accommodating chamber through the first partition wall portion and reach the third accommodating chamber from the inside of the second accommodating chamber through the second partition wall portion,
a terminal block electrically coupled to a coil of the rotation electric machine is provided in a first portion of the second partition wall portion which partitions the first accommodating chamber, and a first connector is provided in a second portion of the second partition wall portion which partitions the second accommodating chamber, and
the first interconnect reaches the third accommodating chamber from the inside of the second accommodating chamber via the first connector.
