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.

Lubrication mechanism for vehicle drive-force transmitting apparatus

A rotorincludes a shaft having a coolant flow passage and a coolant supply port, a rotor corefixed on the shaft and formed of laminated steel plates, and a magnet setprovided in the rotor coreto extend along an axial direction thereof. The rotor corehas a first flow passageprovided near the magnet to extend therealong and a second flow passagethat connects the coolant supply portof the shaftand the first flow passage, thereby constituting a coolant flow path. The second flow passageis formed by overlapping second slitsformed in the respective steel plates at an axially intermediate region A of the rotor core, the formed position of the second slitbeing different for each steel plate combined. The first flow passageand the second flow passagejoin at the axially intermediate region A of the rotor core
