Abstract: A ventilation component 1 includes a ventilation path 10 for allowing ventilation between an inner space 2u and an outer space 2s of a housing 2. The ventilation path 10 is a path for allowing ventilation between the internal space 2u and the outer space 2s when the ventilation component 1 is attached to an edge 2f. The ventilation component 1 includes a supporting portion 12, a gas-permeable membrane 11, a protruding portion 13, and a sealing member 14. The supporting portion 12 surrounds the ventilation path 10. The gas-permeable membrane 11 is bonded to the supporting portion 12 and closes the ventilation path 10 in a ventilatable manner. The protruding portion 13 is a part having a tubular shape, the part being arranged to protrude from the supporting portion 12 and surround one end of the ventilation path 10, the part being configured to be in contact with the edge 2f when the ventilation component 1 is attached to the edge 2f.

Abstract: A ventilation component (1) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The ventilation component (1) is to be attached to a housing (2) having a ventilation opening (5). The ventilation valve (20) includes an elastic body, and is opened and closed by elastic deformation of the elastic body. The structural member (30) supports the gas-permeable membrane (10) and the ventilation valve (20). In an attached state where the ventilation component (1) is attached to the housing (2), ventilation between an inside of the housing (2) and an outside of the housing (2) is carried out via the gas-permeable membrane (10), and the ventilation valve (20) is opened to discharge a gas inside the housing 2 to the outside of the housing 2 when a difference between a pressure inside the housing (2) and a pressure outside the housing (2) is equal to or higher than a predetermined value. The elastic body included in the ventilation valve (20) is formed of a rubber whose rate of change in breaking strength is 95% to 120%.

Abstract: A ventilation member is attached to a through hole of a housing. The ventilation member includes: a support body in which a ventilation path that forms a flow path for gas between the interior and the exterior of the housing; a sealing member that seals between the support body and the housing; a ventilation membrane that is provided on the ventilation path to prevent a liquid and a solid from passing through and to allow gas to pass through; and a contacted portion that is provided to the support body and is formed with a uniform height to surround an end portion opening of the ventilation path. This makes it possible to easily close the ventilation path of the ventilation member.
