摘要：
将变速器外壳(22)的内部分隔为差动室(60)和工作油存积室(65)的存积室分隔板(70)具有：筒状部(71)，其罩住差动齿轮机构(50)的一部分；凸缘部(72)，其从筒状部(71)沿径向延伸出来；差动环形齿轮包围部(73)，其从凸缘部(72)的外周缘部(72a)延伸出来，并且，以与主动小齿轮(44)不相干涉的方式从上方罩住差动环形齿轮(45)的一部分，筒状部(71)、凸缘部(72)以及差动环形齿轮包围部(73)一体成型，在变速器外壳(22)和凸缘部(72)的外周缘部(72a)之间，且至少在位于差动环形齿轮包围部(73)下方的范围内设置有密封部件(80)。
摘要（英）：

A reservoir plate 70 for dividing an inside of a transmission case 22 into a differential chamber 60 and a hydraulic oil storage chamber 65 includes: a cylindrical portion 71 covering a part of a differential gear 50; a flange portion 72 radially extending from the cylindrical portion 71; and a differential ring surrounding portion 73 extending from an outer circumferential edge 72a of the flange portion 72 so that a part of a differential ring gear 45 is covered from above without interfering with a drive pinion gear 44. The cylindrical portion 71, the flange portion 72, and the differential ring surrounding portion 73 are integrally formed with each other. A seal member 80 is interposed between the transmission case 22 and the outer circumferential edge 72a of the flange portion 72 at least in the range below the differential ring surrounding portion 73.
