Abstract
The fluid control valve comprises: a valve seat constituting a part of a valve chamber; a valve body that is installed in the valve chamber and moves in a contacting/separating direction with respect to the valve seat; an actuator configured to move the valve body; and a plunger that transfers power of the actuator to the valve body. The valve body and the plunger are in contact with each other via an inclination suppressing protrusion configured to suppress an inclination of the plunger, the inclination being caused by contact between the valve body and the valve seat.
