PROBLEM TO BE SOLVED: To provide a pressure reducing valve having a biasing means for suppressing the tilt of a piston. SOLUTION: The pressure reducing valve 10 includes: an input chamber 113 to which primary pressurized fluid is supplied; an output chamber 114 connected through a communication path 111 to the input chamber 113 from which secondary pressurized fluid is output; a piston 108 movable to an axial direction along the inner wall of the output chamber 114; a biasing means for biasing the piston 108 to the axial direction; and a valve 110 moving to the axial direction while being interlocked with the piston 108 to open/close the communication path 111. The biasing means is arranged in the output chamber 114, and formed as a coil spring 104 whose valid number of winding is n+0.5 (n is integer). COPYRIGHT: (C)2009,JPO&INPIT
