Abstract

A pressure reducing valve 10 comprises an open-close valve 19 and a piston 16. The open-close valve 19 makes switching between connecting and isolating a primary port 1 P and a secondary port 2P. The piston 16 makes sliding motion inside the cylinder 114 according to a difference between force applied from the pressure regulating chamber 91 and force applied from the pressure reducing chamber 92, thereby opening and closing the open-close valve 19. The open-close valve 19 includes a valve stem 15 and a valve seat fixing member 14. The valve seat fixing member 14 restrains displacement of the piston 16 toward a side upstream of the open-close valve 19 by abutting on an end surface of the piston 16. The valve seat fixing member 14 includes a channel hole 43 communicatively connecting a housing part for the valve stem and the pressure reducing chamber 92.
