Abstract
A driving force transmission apparatus including a tank which reserves lubricating oil in an accommodating space which is interposed between a housing and an inner shaft and an apparatus case which has a cylindrical accommodating portion which accommodates the housing, and in the case, the accommodating portion has an inner circumferential surface which faces an outer circumferential surface of the housing, and the tank has an oil inlet port which is opened to the inner circumferential surface of the accommodating portion and through which the lubricating oil in the accommodating space is let in based on a centrifugal force generated in association with the rotation of the housing when a four-wheel drive vehicle travels forwards in a two-wheel drive mode.
