Abstract
A vehicle motive power transmission apparatus includes: a planetary gear device; an oil pump for sucking oil present in an apparatus case; a one-way clutch that transmits normal-direction rotation output of the planetary gear device to the oil pump, but does not transmit reverse-direction rotation output of the planetary gear device to the oil pump; an oil tank which is provided in the apparatus case, and which is provided with a first introduction portion that receives oil that is splashed upward as a gear in the apparatus case rotates in a normal direction, and a second introduction portion that receives oil that is splashed upward as the gear rotates in a reverse direction; and an oil passageway that supplies the planetary gear device with oil present in the oil tank or oil sucked by the oil pump.
