Abstract

A power transmission device includes a bearing, a differential mechanism, a case that houses the differential mechanism, a pinion gear supported by the case, a wall part that overlaps the case in an axial direction, a plate that is provided between the wall part and the case in the axial direction, and that supports the case with the bearing being interposed, and a parking pawl that is rotatably fixed to the plate in a position that overlaps the plate in the axial direction.

Claims (36)

1. A power transmission device comprising:

a bearing;

a differential mechanism;

a case that houses the differential mechanism;

a pinion gear supported by the case;

a wall part that overlaps the case in an axial direction;

a plate that is provided between the wall part and the case in the axial direction, and that supports the case with the bearing being interposed, and

a parking pawl that is rotatably fixed to the plate in a position that overlaps the plate in the axial direction.

2. The power transmission device according to claim 1 , further comprising

a parking rod, and

a parking rod support part that supports the parking rod to be slidable, wherein

the parking rod support part is fixed to the plate at a position overlapping the plate in the axial direction.

3. The power transmission device according to claim 2 , further comprising

a spring that acts on the parking pawl, wherein

the spring is fixed to the plate.

4. The power transmission device according to claim 3 , wherein

the parking pawl has a portion positioned between the spring and the parking rod support part in a direction intersecting the axial direction.

5. The power transmission device according to claim 4 , wherein

the plate is fixed to a fixing member, and

a density of the plate is greater than a density of the fixing member.

6. The power transmission device according to claim 5 , further comprising

a motor arranged upstream of the differential mechanism, wherein

the differential mechanism overlaps the motor in the axial direction.

7. The power transmission device according to claim 6 , further comprising

a parking gear that engages with the parking pawl, the parking gear being arranged between the plate and the wall part in the axial direction.

8. The power transmission device according to claim 1 , further comprising

a spring that acts on the parking pawl, wherein

the spring is fixed to the plate.

9. The power transmission device according to claim 1 , wherein

the plate is fixed to a fixing member, and

a density of the plate is greater than a density of the fixing member.

10. The power transmission device according to claim 1 , further comprising

a motor arranged upstream of the differential mechanism, wherein

the differential mechanism overlaps the motor in the axial direction.

11. The power transmission device according to claim 1 , further comprising

a parking gear that engages with the parking pawl, the parking gear being arranged between the plate and the wall part in the axial direction.
