Abstract:
A lubrication mechanism for a vehicle drive-force transmitting apparatus including; first and second gears meshing with each other in a meshing region; and a casing storing therein the first and second gears. The lubrication mechanism includes a gutter that extends from an inner wall surface such that oil is received in the gutter and is then dropped from an end of the gutter. The gutter includes a flow-direction changing rib with which the received oil is to be collided whereby a flow direction of the received oil is changed to a direction toward the end of the gutter. The end of the gutter is located on upper side of the meshing region, between first and second vertical planes containing respective first and second axes about which the first and second gears to be rotated, and is located between opposite ends of the meshing region.
