Fluid control valve

A fluid control valve, comprising:

• a valve housing which includes an inflow passage and a discharge passage;
• a valve seat which is disposed between the inflow passage and the discharge passage;
• and
• a valve body which includes a guide portion guided by an inner surface of the valve housing and a seal portion brought into contact with and separated from the valve seat,
• wherein the guide portion of the valve body includes a flat surface and a tapered surface inclined with respect to the flat surface so as to be tapered toward a side of the seal portion side from an edge of the flat surface on a seal portion side in an axial direction of the valve body,
• wherein a dimension difference (L1) between a radius of a first axial end edge of the tapered surface and a radius of a second axial end edge of the tapered surface is smaller than a clearance (L2) between the flat surface and the inner surface of the valve housing in a state in which the valve body is disposed coaxially with the valve housing, and
• wherein a concave portion extending from the flat surface to the tapered surface is formed in the valve body, the concave portion extending at least partially in a circumferential direction along both the flat surface and the tapered surface.
