Power transmission device
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.
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.
