Abstract

A power transmission device includes a gear mechanism, a wall part that overlaps with the gear mechanism in an axial direction, a plate provided between the wall part and the gear mechanism in the axial direction, and a park lock mechanism. The park lock mechanism has a parking pawl on a side of a surface of the plate facing the wall part. The park lock mechanism has a manual shaft and/or a detent mechanism on a side of a surface of the plate facing the gear mechanism.

Claims (27)

1. A power transmission device comprising:

a gear mechanism;

a wall part that overlaps with the gear mechanism in an axial direction;

a plate provided between the wall part and the gear mechanism in the axial direction; and

a park lock mechanism, wherein

the park lock mechanism has a parking pawl on a side of a surface of the plate facing the wall part, and

the park lock mechanism has a manual shaft and/or a detent mechanism on a side of a surface of the plate facing the gear mechanism.

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

by the parking rod moving, acting on a leverage point of the parking pawl, a hook part that is an action point of the parking pawl engages with a parking gear.

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

a shelf part above a horizontal line that passes through a rotation center of the gear mechanism, and

the manual shaft and/or the detent mechanism are arranged above the shelf part.

4. The power transmission device according to claim 3 , wherein the shelf part defines an oil hole.

5. The power transmission device according to claim 4 , wherein an oil catch member is formed above the shelf part.

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

a motor arranged upstream of the gear mechanism, and

the gear mechanism overlaps the motor in the axial direction.

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

a shelf part above a horizontal line that passes through a rotation center of the gear mechanism, and

the manual shaft and/or the detent mechanism are arranged above the shelf part.

8. The power transmission device according to claim 7 , wherein

the shelf part defines an oil hole.

9. The power transmission device according to claim 7 , wherein

an oil catch member is formed above the shelf part.

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

a motor arranged upstream of the gear mechanism, and

the gear mechanism overlaps the motor in the axial direction.
