ブ装置。A switching valve that selectively introduces hydraulic oil from a hydraulic pump to a hydraulic clutch is provided with a relief valve for adjusting the clutch oil pressure having a relief piston, and a trimming plug that adjusts the relief pressure set in the relief valve for adjusting the clutch oil pressure. A relief valve control device provided between the relief piston and the trimming plug for generating low back pressure in the oil passage after passing through the relief valve to generate latch operation hydraulic pressure when necessary. The force that balances the spring is obtained by dividing and allocating the pump hydraulic pressure and the low hydraulic pressure after passing through the relief piston to the back of the relief piston, and by appropriately setting the proportion of the balancing force due to the pump hydraulic pressure and the low hydraulic pressure. Fluctuations in the clutch operating oil pressure due to increases and decreases in oil amount and temperature changes are suppressed, and the clutch operating oil pressure increases more slowly when the hydraulic pump rotates at high speed than when the hydraulic pump rotates at low speed. A hydraulic clutch control valve device characterized by:
