    • A casing body of a transmission casing has an oil pan mounting flange including an oil pan joint surface for joining an end surface of the oil pan, and a housing mounting flange including a housing joint surface for joining an end surface of a housing. The oil pan mounting flange and the housing mounting flange are provided substantially perpendicularly to each other. A reinforcing rib is formed parallel to the oil pan joint surface to reinforce the casing body. A pocket part is formed on the back surface of the reinforcing rib opposite to the direction of the oil pan joint surface, and a processing/assembling reference hole is formed in the reinforcing rib at a location of the rib where the pocket part is formed. As the reference hole is obtained without protruding the flanges, a greater degree of design freedom is provided and material costs are reduced. Further, if the flange is clamped, a claiming force is not exerted on the reference hole, thereby preventing deformation or displacement of the hole.
    • 变速器壳体的壳体具有油盘安装凸缘,该油盘安装凸缘包括用于连接油盘的端面的油盘接头表面和包括用于接合壳体的端面的壳体接合表面的壳体安装凸缘。 油盘安装法兰和壳体安装法兰基本垂直地设置。 加强肋平行于油盘接头表面形成以加强壳体。 在加强肋的与油盘接合面的方向相反的后表面上形成有袋部,并且在形成有袋部的肋的位置处,在加强筋中形成有加工/组装基准孔。 由于在不突出凸缘的情况下获得参考孔,因此提供更大程度的设计自由度并降低材料成本。 此外,如果法兰被夹紧,则不会在基准孔上施加声明力,从而防止孔的变形或位移。
