Abstract
A valve structure includes: a valve seat part furnished with a valve hole portion having a valve hole connecting a first gas chamber to a second gas chamber, and a valve-body supporting wall part laterally extending from the valve hole portion; an elastic valve-body member furnished with a first elastic platelike section disposed paralleling the valve hole portion, and a second elastic platelike section extending from the first elastic platelike section, wherein the first elastic platelike section is elastically deformable against the second elastic platelike section under pressure differential between the first gas chamber and the second gas chamber such as to open the valve hole; and an elastic pressing member arranged paralleling the second elastic platelike section such as to elastically deform together with the elastic valve-body member, and being of planar form configured so as to expose the first elastic platelike section.
