<p>PROBLEM TO BE SOLVED: To restrict an increase in axial length of the entire device while improving the assembly of a vehicle driving device.SOLUTION: The present invention relates to a vehicle drive device 1 including a first module M1 and a second module M2 fitted to each other in an axial direction. The first module M1 includes a first rotation member 15 and a second rotation member 24. The second module M2 includes a third rotation member 35 and a fourth rotation member 44. The engagement phase pitch of the second engagement part of the second rotation member 24 with the fourth engagement part of the fourth rotation member 44 is larger than the engagement phase pitch of the first engagement part E1 of the first rotation member 15 with the third engagement part E3 of the third rotation member 35. In an assembled state, the axial length of a second overlapping region L2 of the second and fourth rotation members 24, 44 is longer than the axial length of the first overlapping region L1 of the first and third rotation members 15, 35.</p> |
