The invention provides a vehicle driving force distribution device including: a differential gear 2; a driving force transmission device 3; and a case member 4 having a first accommodating chamber 4a accommodating the differential gear 2 and a second accommodating chamber 4b accommodating the driving force transmission device 3. The case member 4 has a first flow passage 44 that allows lubricating oil to flow from the first accommodating chamber 4a into the second accommodating chamber 4b, and a second flow passage 45 that allows lubricating oil to flow from the second accommodating chamber 4b into the first accommodating chamber 4a. In a two-wheel drive mode, lubricating oil flows from the second accommodating chamber 4b into the first accommodating chamber 4a through the second flow passage 45. In a four-wheel drive mode, lubricating oil flows from the first accommodating chamber 4a into the second accommodating chamber 4b through the first flow passage 44.
