<p>The pressure receiving surface (11A) of a stepped support (11) in a through-hole (10) in a container main body (1) is opposed to the pressing surface (14A) of the flange (14) of a supply and exhaust sleeve (13). When the flange (14) of the supply and exhaust sleeve (13) is loaded, it is deformed and the pressing surface (14A) is pressed against the pressure receiving surface (11A) to conform with the latter.</p> |
