PURPOSE:To make small in size an automatic transmission gear by arranging components of oil pump and a oil pump itself in a particular configuration on an oil pump housing portion mounted to a converter housing in a particular manner. CONSTITUTION:In a transaccel-casing of an automatic transmission gear 20 consisting of a transmission casing 22 and a converter housing 24, an oil pump housing portion 24b is integrated with said housing 24 so as to separate said casing 22 and said housing 24. In an circular concave 24c formed on said housing portion 24b, for example a vane pump 27 is disposed, and on the surface of casing 22 side of said housing portion 24b, an oil pump cover 30 is mounted through a separator 29, thereby obviating the necessity of a space for mounting a conventional oil pump housing. |
