To provide a vehicular driving device in which excessive load can be prevented from being input into a pump rotor.SOLUTION: When a pump drive shaft 48 is relatively moved toward one end part side in an axial direction with respect to a wall part 40a of a second case member 40, a flange part 48f abuts on a cylinder protrusion 40k formed at the wall part 40a of the second case member 40 before a difference-in-level part 48d abuts on an inner rotor 50, and the relative movement of the pump drive shaft 48 is regulated. Therefore, even if an excessive load acts in a direction in which the pump drive shaft is relatively moved to the wall part 40a of the second case member 40 toward one end part side in the axial direction from the pump drive shaft 48, the pump drive shaft 48 is received at the cylinder protrusion 40k formed at the wall part 40a of the second case member 40 by the pump drive shaft 48 before the difference-in-level part 48d abuts on the inner rotor 50, and therefore, the excessive load can be prevented from being input into the inner rotor 50.SELECTED DRAWING: Figure 3 【課題】ポンプロータに過大な荷重が入力されることを防ぐことができる車両用駆動装置を提供する。【解決手段】ポンプ駆動軸４８が第２ケース部材４０の壁部４０ａに対して軸方向の一端部側に向けて相対移動させられると、段差部４８ｄがインナロータ５０に当接する前に鍔部４８ｆが第２ケース部材４０の壁部４０ａに形成された円筒突部４０ｋに当接してポンプ駆動軸４８の相対移動が規制される。このため、ポンプ駆動軸４８から前記軸方向の一端部側に向けて第２ケース部材４０の壁部４０ａに対して相対移動する方向に過大な荷重が作用したとしても、段差部４８ｄがインナロータ５０に当接する前に鍔部４８ｆでポンプ駆動軸４８が第２ケース部材４０の壁部４０ａに形成された円筒突部４０ｋに受け止められるので、インナロータ５０に過大な荷重が入力されるのを防ぐことができる。【選択図】図３
