Abstract

A part of oil sucked by an oil pump is circulated to an oil pan through a hydraulic control circuit, an oil cooler and an oil passage provided in a transmission case and the oil pan. The oil guided to the oil pan is gushed out from a discharge port of the oil passage toward a suction port of an oil strainer communicating with the oil pump. The discharge port of the oil passage is disposed opposite and adjacent to the suction port of the oil strainer so that only the oil containing a small number of bubbles is sucked by the oil pump.
