ABSTRACT:
The invention provides a novel dual-membered suctional gasket which has a reliable function to fit and fix the gasket to an object to be sealed, and also provides an effective suction effect and air venting function. For that purpose, the gasket which has a function to prevent fluid from leaking when compressed, comprises an inner sealing member1and outer sealing member2arranged on a surface perpendicular to a compressing direction; and a plurality of connecting members3for connecting and fixing the inner sealing member1and the outer sealing member2together. Suction cup structures are formed, when a proper amount of air closed between the inner sealing member and the outer sealing member is vented from the inner sealing member, the outer sealing member or the both sealing members by compressing the dual-membered gasket.
