The present invention provides a transfer (22, 200) for a four-wheel drive vehicle which can suppress the loss of driving power transferred to main drive wheels from a driving power source. The four-wheel drive vehicle is configured to separate a propeller shaft from a power transmission path between auxiliary drive wheels and a driving power source during a period of driving as a two-wheel drive of the four-wheel drive vehicle, and includes a second output rotating member (44) and an oil pump (120). The second output rotating member (44) is configured to output driving power to the propeller shaft. The oil pump (120) is configured to rotationally drive in conjunction with the rotation of the second output rotating member (44) via a first one-way clutch. The first one-way clutch is configured to supply lubrication oil to a wet clutch (48) when the four-wheel drive vehicle moves forward by the four-wheel drive. The oil pump (120) is configured to stop supplying the lubrication oil to the wet clutch (48) when the four-wheel drive vehicle moves forward by the two-wheel drive.

    사륜 구동 차량의 상기 트랜스퍼 (22 ; 200), 상기 사륜 구동 차량은 사륜 구동 차량의 이륜 구동시에 있어서 프로펠러 샤프트를 부구동륜과 구동력원 사이의 동력 전달 경로로부터 분리시키도록 구성되고, 제 2 출력 회전 부재 (44) 및 오일 펌프 (120) 를 포함한다. 제 2 출력 회전 부재 (44) 는, 상기 프로펠러 샤프트에 구동력을 출력하도록 구성된다. 상기 오일 펌프 (120) 는, 제 1 원웨이 클러치를 통하여 상기 제 2 출력 회전 부재 (44) 의 회전에 연동하여 회전 구동하도록 구성된다. 상기 제 1 원웨이 클러치는, 상기 사륜 구동 차량이 상기 사륜 구동으로 전진 주행할 때에 있어서 상기 습식 클러치 (48) 에 윤활유를 공급하도록 구성된다. 상기 오일 펌프 (120) 는, 상기 사륜 구동 차량이 상기 이륜 구동으로 전진 주행할 때에 있어서 상기 습식 클러치 (48) 에 윤활유를 공급하는 것을 정지시키도록 구성된다.
