Operate the valve 27 and operate the hydraulic clutch 18.19.
In an automatic transmission device with a mission that automatically changes gears by selectively operating the oil pump, pressure oil is introduced from the oil pump 44 to the control valve 27 via a relief valve 45. The pressure oil branched on the pump 44 side is guided to each of the solenoid valves 30 and 31, and the relief valve 45 is bypassed to form a bypass 51 via the solenoid valve 50 while reaching the control valve 27. and each of the solenoid valves 30°3
1, the solenoid valve 50 is operated so as to close the bypass 51 only when pressure oil must be supplied to the 1, and open the bypass 51 at other times. Device.
