Abstract
A hybrid drive unit that includes an input shaft connected to an engine; an output shaft connected to wheels; a first rotary electric machine; a second rotary electric machine connected to the output shaft; a power distribution device that distributes a rotational driving force of the input shaft to the output shaft and to the first rotary electric machine; a second rotary electric machine fixing device that selectively fixes a rotor of the second rotary electric machine; and a transmission cutoff device capable of cutting off transmission of rotation between the output shaft and the second rotary electric machine at least in a state when the rotor of the second rotary electric machine is fixed.
