ABSTRACT:
A detent mechanism for a pressure control valve adapted to control the extent of deflection of each of pressure control springs to control pressure on a secondary side of each of spools to a level depending on the deflection, which is capable of causing each of solenoids to be simplified or small-sized. For this purpose, the control lever is provided with a plurality of suction elements and the solenoids are arranged to suck suction elements thereon. A position at which each of the suction elements is sucked on the solenoid is defined outside of a position at which push rods each are abutted against a forcing section of the control rod.
