Abstract: 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.
