一种密封构造,位于油流出部与油流入部之间,该油流出部形成于第一壳体,该油流入部形成于第二壳体,并且具有与油流出部的端面隔开间隙相对的端面,所述密封构造包含:环状的第一密封部件,配置在形成于油流出部以及油流入部中的一个的油路的出口或者入口侧且直径比该油路的直径大的扩径孔部内,并与位于油路和扩径孔部的边界的阶梯面抵接;以及环状的第二密封部件,比第一密封部件硬,配置在扩径孔部内,与该第一密封部件、和油流出部以及油流入部中的另一个的端面抵接。

    A seal structure between an oil outlet formed in a first case and an oil inlet formed in a second case and having an end face facing an end face of the oil outlet with a clearance between the end faces, the seal structure including an annular first seal disposed in an increased-diameter hole, which is formed on an outlet side or an inlet side of an oil passage in one of the oil outlet and the oil inlet and has a larger diameter than the oil passage, such that the first seal contacts a step surface located at a boundary between the oil passage and the increased-diameter hole; and an annular second seal harder than the first seal and disposed in the increased-diameter hole such that the second seal contacts the first seal and the end face of the other of the oil outlet and the oil inlet.
