摘要： A counter gear mechanism includes: a fifth gear in mesh with a third gear; a sixth gear in mesh with a fourth gear; and a seventh gear in mesh with a differential input gear. The seventh gear is disposed between the fifth gear and the sixth gear in an axial direction. A switching mechanism is disposed between the third gear and the fourth gear in the axial direction. The switching mechanism makes switching among: a state in which the third gear is coupled to a second input member; a state in which the fourth gear is coupled to the second input member; and a state in which the third gear and the fourth gear are decoupled from the second input member. This structure is able to make an entirety of an apparatus compact in size in the axial direction when the apparatus includes the switching mechanism to change the speed ratio between the second input member, which is drivingly coupled to an internal combustion engine, and output members.

摘要： A vehicle drive device is provided that can suppress the increase in dimension in the radial direction while ensuring a sufficient speed reduction ratio. Two driving force sources are arranged on a first axis, two output members are arranged on a second axis, two counter gear mechanisms are arranged on a third axis. A planetary gear mechanism is configured to transmit rotation from the two counter gear mechanisms to the output members, and is disposed so as to overlap with both of the two counter gear mechanisms as seen in an axial direction along and axial direction.

摘要： A first case portion includes an end wall portion disposed on a first axial side with respect to a transmission. A second case portion is disposed on the first axial side with respect to a rotor of a rotary electric machine, and includes a first support portion that supports a rotor shaft and a second support portion disposed on a second axial side with respect to the rotor of the rotary electric machine to support the rotor shaft. The second support portion includes a bearing attachment portion to which a rotor bearing for supporting the rotor shaft is attached, and radially extending portion that extends from bearing attachment portion toward an outer side in a radial direction. A speed reducer is disposed between the radially extending portion and the end wall portion in axial direction to face the radially extending portion and the end wall portion in the axial direction.
