Abstract
The present invention provides a sealing bead in which linearly acting surface pressures are generated at its portions which does not directly contribute to generating the linearly acting surface pressures in the conventional sealing bead, thereby enhancing the efficiency for generating linearly acting surface pressures with respect to a displacement amount of height of the sealing bead. A peripheral portion of a sealing bead between a bent position and an opening edge is bent up or down so as to form a pre-determined degree of an angle with respect to a corresponding flange surface. With this structure, linearly acting surface pressures are generated at the opening edge that, in the conventional bead, does not directly contribute to generating linearly acting surface pressures.
