Claims

[Claims for Utility Model Registration] The system includes a pump body that is integrally provided with a first housing that houses a fluid transmission device, and a pump cover that is integrally fixed to the pump body. an oil pump that generates an oil pump; and a second housing that is integrally fixed to the first housing and houses a transmission mechanism, and is provided on an end surface of the second housing on the oil pump side and an outer periphery of the oil pump. an oil passage that opens opposite to the side portion; an oil passage that extends outward from the pump cover to a position where the opening of the oil passage exists; and a through hole that corresponds to the opening of the oil passage; an overhanging flange formed with an overhanging flange, and at least one of the contact surfaces of the pump cover and the pump body including the overhanging flange that are brought into close contact with each other is provided in a state that is open to the other, and the through hole is provided in the oil passage. A hydraulic system for an automatic transmission, comprising: a recess that forms a communicating oil passage between the contact surfaces through which the communication oil passage is communicated.
