PROBLEM TO BE SOLVED: To compactly arrange an oil pump and an oil pressure control valve adjacent to each other in a transmission housing. SOLUTION: This hydraulic control device for a transmission is provided with a first oil pressure control valve 60 connected to a side end surface S1 of a first housing H1, an oil pump 50 connected to the first oil pressure control valve 60, and a transmission input shaft 1 arranged in the transmission housing freely to be rotated. The oil pump 50 is formed of pump casings 51 and 54 connected to a valve body of the first oil pressure control valve 60 and an outer rotor 52 and an inner rotor 53 arranged inside of the casings. The transmission input shaft 1 is inserted into the pump casing, and fitted for connection to the inner rotor 53 to drive the inner rotor 53 for rotation. This oil pump 50 sucks the operating fluid from a bottom part of the transmission housing, and supplies the operating fluid to the first oil pressure control valve 60 through the connection part to the valve body. |
