A counter gear mechanism (31) includes: a fifth gear (G5) in mesh with a third gear (G3); a sixth gear (G6) in mesh with a fourth gear (G4); and a seventh gear (G7) in mesh with a differential input gear (GD). The seventh gear (G7) is disposed between the fifth gear (G5) and the sixth gear (G6) in an axial direction (L). A switching mechanism (51) is disposed between the third gear (G3) and the fourth gear (G4) in the axial direction (L). The switching mechanism (51) makes switching among: a state in which the third gear (G3) is coupled to a second input member (13); a state in which the fourth gear (G4) is coupled to the second input member (13); and a state in which the third gear (G3) and the fourth gear (G4) are decoupled from the second input member (13). 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.
