ンプ。[Claims for Utility Model Registration] 1. A housing body which is provided with a cover that is fitted to the housing body, and which is attached to the automatic transmission with the cover facing the housing body and which extends over the housing body and the cover. A hydraulic oil passage is formed through which the hydraulic oil used in and a cover side communication part, the main body side inflow/outflow part and the cover side inflow/outflow part each extend from the automatic transmission side to the opposite side, and the main body side communication part and the cover side communication part each flow out from the main body side. In an oil pump for an automatic transmission, which is connected to an inlet and a cover-side inlet/outlet and are aligned with each other at the mating surfaces of the housing main body and the cover, both communicating portions of the hydraulic oil passage are on a straight line that diagonally intersects the mating surfaces. An oil pump for an automatic transmission characterized by being located in. 2. The automatic transmission according to claim 1, wherein a port portion formed by casting is provided at a joint portion between the main body side communication portion and the cover side communication portion between the housing body and the cover. oil pump. 3 Connection angle between the main body side inflow/outflow part and the main body side communication part,
3. The oil pump for an automatic transmission according to claim 1, wherein connection angles between the cover side inflow/outflow portion and the cover side communication portion are obtuse angles.
