A hybrid drive unit includes an input member connected to an engine; an output member connected to wheels; a rotary electric machine; and a pair of planetary gear units that each have at least three rotation elements. The hybrid drive unit is capable of realizing a plurality of shift speeds, one planetary gear unit of the pair of planetary gear units comprises at least one fixed rotation element that serves as a rotation element whose rotation is stopped by a non-rotating member, the one planetary gear unit serving as a decelerating planetary gear unit that decelerates a rotation of the rotary electric machine and transmits a decelerated rotation to the output member at all of the shift speeds, and the other planetary gear unit of the pair of planetary gear units serves as a shifting planetary gear unit that transmits a rotation of the input member to the output member. |
