Joint d'étanchéité

Gasket

Abstract

A gasket that, when it is tightened from both sides by flanges etc., elastically deforms to produce reaction force acting against the tightening force, achieving improved sealing ability, and that is manufacturable at low cost by press working. One or more first annular curved ridges (12, 13) are formed on one side of a plate body (27) having a round hole (11) at its center and formed of an elastic material, and annular curved grooves (14, 15) are formed on the other side, at portions corresponding to the first annular curved ridges (12, 13). One or more second annular curved ridges (16) are formed on the other side, at positions not superposed on the first annular curved ridges (12, 13), and annular curved grooves (17) are formed on one side, at positions corresponding to the second annular curved ridges (16). Elastically deformable annular connection sections (18, 19) are formed between the first annular curved ridges (12, 13) and the second annular curved ridges (16).
