第１項記載の減圧弁。[Claims for Utility Model Registration] (1) A valve body is provided between a primary flow path connected to a fluid pressure source and a secondary flow path connected to a fluid usage part, and the valve body is displaceable. The pressure reducing valve adjusts the fluid pressure obtained in the secondary flow path by changing the cross-sectional area of an orifice constituted by the valve body and the valve seat, wherein the valve body is and a pressure display section that externally displays the fluid pressure in the secondary flow path based on the displacement of a pressure regulating mechanism that adjusts the fluid pressure obtained in the secondary flow path by displacing the Features a pressure reducing valve. (2) The pressure regulating mechanism is an adjusting screw that is screwed onto the pressure reducing valve body and controls the amount of displacement of the valve body by an axial displacement generated by rotation from the outside, and the pressure regulating mechanism is a display portion is located inside the pressure reducing valve body and is formed on a flange that is axially displaced together with the adjustment screw and on the pressure reducing valve body;
The pressure reducing valve according to claim 1, characterized in that the pressure reducing valve comprises a window portion through which the amount of displacement of the flange can be visually confirmed from the outside.
