A first output hydraulic port that outputs a first output hydraulic pressure, a first signal hydraulic port that receives a first signal hydraulic pressure that pushes the spool in one direction, and a first signal hydraulic port that pushes the spool in a direction opposite to the first signal hydraulic pressure. A first output signal hydraulic port to which the output hydraulic pressure is returned; a first input hydraulic port that is closed when the load due to the first output hydraulic pressure is greater than the load due to the first signal hydraulic pressure; and a first input hydraulic port that communicates with the first output hydraulic port at that time. a drain port, a second output hydraulic port that communicates with the drain port during a period when the first signal hydraulic pressure is applied, a second input hydraulic port that is closed during the period, and a spool in a direction opposite to the first signal hydraulic pressure. The first signal hydraulic pressure and the second signal hydraulic pressure are selectively inputted, and when the second signal hydraulic pressure acts, the second input hydraulic pressure is input. A pressure regulating switching valve characterized in that the port and the second output hydraulic port communicate with each other, the first output hydraulic port and the drain port communicate with each other, and the first input hydraulic port is closed.
