Abstract
In order to improve sealing performance when the open end of a tank is swaged and thereby secured inside an annular groove the surface of which is formed in a substantially rectangular shape with a seal material between the groove an the tank, flange parts protrude in a fan shape at the four corners of the seal material, and those flange parts are pressed by the corner sections of the annular groove, thereby preventing the seal material from moving in the corner sections.
