Vehicle drive device

A vehicle drive device comprising:

• an input member drivingly connected to a driving force source;
• a pair of output shafts drivingly connected to wheels;
• a speed reducer configured to reduce a speed of rotation of the input member;
• and
• a differential gear device configured to distribute the rotation of the input member transmitted via the speed reducer to the pair of output shafts, wherein
• assuming that an axial direction is a direction along an output rotation axis that is a rotation axis of the pair of output shafts, a first axial side is one side in the axial direction, a second axial side is the other side in the axial direction, a radial direction is a direction orthogonal to the output rotation axis, and a circumferential direction is a direction about the output rotation axis,
• the differential gear device includes a differential case and a differential gear mechanism housed in the differential case,
• the differential gear mechanism includes a shaft member formed so as to extend along the radial direction, a plurality of first bevel gears rotatably supported by the shaft member and disposed separately in the circumferential direction, and a pair of second bevel gears disposed separately on both sides of the shaft member in the axial direction and meshing with the plurality of first bevel gears,
• the pair of second bevel gears is connected to the pair of output shafts so as to rotate integrally with the pair of output shafts, and
• assuming that one of the pair of second bevel gears that is disposed on the second axial side with respect to the shaft member is a specific bevel gear and one of the pair of output shafts that rotates integrally with the specific bevel gear is a specific output shaft,
• an engaging portion provided on the specific output shaft and an engaged portion provided on the specific bevel gear engage with each other so as to restrict relative movement in the circumferential direction and the radial direction between the specific output shaft and the specific bevel gear, and
• the specific bevel gear is supported on the differential case in the axial direction and is not supported on the differential case in the radial direction.
