Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the lid seal of an air locking type by using an O ring as it is for a pressure container or a vacuum container. SOLUTION: In this lid sealing device of an automatic opening/closing type capable of air locking by using the O ring 1 as packing, the shape of a groove part 3 is turned to the annular seal part of a fixed circle, the average clearance of a groove width (G) to the thickness (W) of the O ring made of synthetic rubber is turned to 0-0.3 mm and the O ring is provided so as to be moved and deformed at the time of the supply of pressurizing air or vacuum suction. Also, a groove depth is made shallow, the moving amount of the O ring is shortened and the lid sealing device is used for a digester or the like.
