Abstract
A fluid control valve improves position stability of a displacement expanding mechanism, and includes an actuator for driving the valve body, and the displacement expanding mechanism interposed between the valve body and the actuator to expand displacement of the actuator and transmit the displacement to the valve body. The displacement expanding mechanism includes an input member that is displaced upon receiving a driving force from the actuator, and a plurality of lever members that are disposed around a central axis of the valve body between the input member and the valve body, and expand displacement of the input member and transmit the displacement to the valve body. The plurality of lever members each have a contact surface with which the input member comes into contact to serve as a force point portion. The contact surface forms a downward gradient toward the central axis of the valve body.
