<p>Left and right partitions (15G), which separate a differential mechanism (21) and left and right axle tubes (17), are provided to a differential case (14). A plurality of oil flow ports (39) are provided to the partitions (15G). In this setting, on a plane of each partition (15G), if a fan-shaped region is denoted as alpha, said fan-shaped region having an angle of less than 90 degrees and being positioned closer to a pinion gear (20) than a downward-oriented axis (Z-Z), which passes through the center of rotation (O) of the differential mechanism (21) at a position lower than an axis (X-X) of rotating shafts (25), each oil flow port (39) is positioned in a C-shaped region (delta) that has disengaged from the fan-shaped region (alpha).</p> |
