摘要：A tubular member is disposed between a pair of drive pinions at the right andleft and shaft insertion holes for insertion of the pinion shafts for axial support of thedifferential pinions are formed in the tubular member. First lubrication grooves forinduction of the lubricating oil to the shaft insertion holes are formed on the innercircumferential surface of the tubular member. Second lubrication grooves extendingfrom inside positions of the first lubrication grooves in radial directions of the tubularmember toward the axial supporting parts of the differential pinions to reach theattachment parts of washers on the rear surfaces of the differential pinions are formedon the outer circumferential surfaces of the pinion shafts. The lubricating oil collected bythe tubular member is supplied efficiently to the axial supporting parts of the differentialpinions with guidance of the first lubrication grooves and the second lubrication grooves.
