VEHICULAR DRIVING DEVICE

To enable use of a common driving source between an oil pump and a parking lock mechanism and secure rotation torque for operating the packing lock mechanism efficiently.SOLUTION: A vehicular driving device includes: a motor: a first rotary shaft member; a first one-way clutch connected to the first rotary shaft member; an oil pump which is connected to the first rotary shaft member through the first one-way clutch so as to operate in response to rotation of the motor in a first rotation direction; a second rotary shaft member which is offset relative to the first rotary shaft member in a radial direction; a speed reduction mechanism provided between the first rotary shaft member and the second rotary shaft member; a second one-way clutch which is connected to the second rotary shaft member so that the second rotary shaft member rotates in response to rotation of the motor in a second rotation direction; and a mechanism driving member which is provided at the second rotary shaft member and drives a parking lock mechanism. The mechanism driving member is disposed at the opposite side of the oil pump across the speed reduction mechanism in an axial direction.SELECTED DRAWING: Figure 5 【課題】オイルポンプとパーキングロック機構との間で駆動源の共用化を図りつつ、パーキングロック機構を作動させるための回転トルクを効率的に確保する。【解決手段】モータと、第１回転軸部材と、第１回転軸部材に接続される第１ワンウェイクラッチと、モータの第１回転方向の回転に応じて作動するように第１回転軸部材に第１ワンウェイクラッチを介して接続されるオイルポンプと、第１回転軸部材に対して径方向にオフセットした第２回転軸部材と、第１回転軸部材と第２回転軸部材の間に設けられる減速機構と、モータの第２回転方向の回転に応じて第２回転軸部材が回転するように、第２回転軸部材に接続される第２ワンウェイクラッチと、第２回転軸部材に設けられパーキングロック機構を駆動する機構駆動部材とを含み、機構駆動部材は、軸方向で減速機構を挟んでオイルポンプの反対側に配置される、車両用駆動装置が開示される。【選択図】図５
