<P>PROBLEM TO BE SOLVED: To provide a hydraulic control device for a vehicle drive device having a simple structure, by which provision of a dedicated linear solenoid valve for regulating line pressure can be unnecessary. <P>SOLUTION: A hydraulic pressure regulating part 1A of the hydraulic control device includes: a primary regulator valve 21 for regulating hydraulic pressure from an oil pump 15 to line pressure P<SB POS="POST">L</SB>according to input pressure input to a control oil chamber 21a; a linear solenoid valve SLU for regulating and outputting engagement pressure P<SB POS="POST">K0</SB>supplied to a hydraulic servo 40 of a clutch K-0 capable of connecting power transmission between an internal combustion engine and a transmission; and oil paths e4, e5, e6 enabling input of the engagement pressure P<SB POS="POST">K0</SB>for the linear solenoid valve SLU to the control oil chamber 21a of the primary regulator valve 21. In the primary regulator valve 21, the line pressure P<SB POS="POST">L</SB>is regulated according to the engagement pressure P<SB POS="POST">K0</SB>, so that with a simple structure, the dedicated linear solenoid valve for regulating the line pressure becomes unnecessary. <P>COPYRIGHT: (C)2013,JPO&INPIT |
