Abstract:
An object of the present invention is to achieve favorable sealability by a simple and low-cost structure using an O-ring. A sealing structure according to the present invention is provided with: a first sealing surface formed in an annular shape on a first container structural member configuring a housing (container); a second sealing surface overlaid on the first sealing surface, formed in annular shape on a second container structural member configuring the housing; a plurality of concentric O-ring grooves formed on at least one of the first sealing surface and second sealing surface; and a plurality of O-rings fitted into the plurality of O-ring grooves. The filling ratio of the O-ring in the O-ring groove positioned on an outer side of the housing is larger than the filling ratio of the O-ring in the O-ring groove positioned on an inner side of the housing.
