The other end of the spool, which is biased by a spring, is brought into contact with the adjuster rod, two ports connected to the main circuit are opened around the spool, and an annular groove is formed on the outer periphery of the spool to communicate between both ports as the spool is displaced. two piston pins are arranged in series in a bottomed through passage formed inside the spool, one piston pin is brought into contact with the adjusting rod, and one is placed at the mutual contact point of these piston pins. A pressure control valve for a hydraulic transmission device, characterized in that the hydraulic oil in one port is communicated with the end of the piston pin that contacts the spool so as to guide the hydraulic oil in the other port.
