<p>PROBLEM TO BE SOLVED: To allow an operation part in a fluid control element to operate independently of a pressure inside a control space so as to improve durability. SOLUTION: A fluid control element is provided with at least two fluid ducts 16 opened to a control space 12 formed in a housing 10, at least one sealing seat part 14 arranged in the control space 12 and communicated with one of the fluid ducts 16, and a movable lug part 30 extending into the control space 12. The lug part 30 is housed in an elastic element so as to cover the sealing seat part 14 and constitutes one arm in two arms constituting a lever. The other arm in the lever serves as an operation arm 22 and protrudes from the control space 12. As the lever is supported as two rotary joints arranged opposedly in the width direction longitudinal direction of the lever, the lever can be moved without respect to a pressure.</p> |
