Abstract: A ventilation component (1a) is to be attached to a housing (2) at a ventilation opening (5). The ventilation component (1a) includes a gas-permeable membrane (10), a ventilation valve (20), and a structural member (30). The structural member (30) has an inner space (40), and at least one of a first ventilation path (51) and a second ventilation paths (52). The inner space (40) is a space accommodating the gas-permeable membrane (10) and/or the ventilation valve (20). The first ventilation path (51) allows the inner space (40) to communicate with an external space of the ventilation component (1a). The first ventilation path (51) has a first inner opening (51i) and a first outer opening (51e), and the first inner opening (51i) faces the first outer opening (51e). The first inner opening (51i) and the first outer opening (51e) are present along a plane parallel to an outer surface (2s) of the housing. The second ventilation path (52) has a second inner opening (52i) and a second outer opening (52e), and the second inner opening (52i) is present without facing the second outer opening (52e).

Abstract: A ventilation component (1a) includes a valve body portion (10), a shaft portion (20), a ventilation path (15), and a gas-permeable membrane (30). The valve body portion (10) has an umbrella cloth shape. The shaft portion (20) extends in a normal direction of the valve body portion (10). The shaft portion (20) supports the valve body portion (10). The ventilation path (15) extends through the shaft portion (20) in the normal direction of the valve body portion (10). The gas-permeable membrane (30) closes the ventilation path (15) such that ventilation can occur. In a state where the ventilation component (1a) is fixed to a housing (50), the valve body portion (10) covers a peripheral opening (55) and an outer circumferential portion of the valve body portion (10) is in contact with an outer surface (52a) of the housing (50) such that a flow of gas passing through the peripheral opening (55) is blocked. In addition, ventilation occurs between an inner space (51) and an external space (52) via the gas-permeable membrane (30). When a pressure difference obtained by subtracting a pressure of the external space (52) of the housing (50) from a pressure of the inner space (51) of the housing (50) is equal to or higher than a predetermined value, the valve body portion (10) elastically deforms to be away from an outer surface (52a) to release the pressure of the inner space (51).

Abstract: A ventilation member of the present disclosure comprises: a support having a through hole that serves as an air passage between inside and outside of a housing upon attaching the support to an opening of the housing; and an air-permeable membrane disposed on the support and closing the through hole. The support comprises: a supporting portion in which the through hole is provided and at which the air-permeable membrane is disposed, and an insertion portion extending from the supporting portion and having an end with a hook, wherein the insertion portion bends in a direction closer to a central axis of the ventilation member while the hook is passing through the opening by being inserted into the opening, and fixes the ventilation member to the opening with the hook engaging the housing after passing through the opening. The ventilation member has a stopper portion with which bending of the insertion portion in the direction is restricted within an elastically deformable range of the insertion portion during the insertion into the opening. A ventilation member of the present disclosure can be reliably fixed to an opening of a housing with the insertion portion, even when the insertion portion is inserted into the opening at an angle.

Abstract: The aeration member is a porous body for discharging water vapor in the interior of a closed lamp housing. The aeration member has small pore diameter structures for preventing infiltration of liquid water and contaminants into the lamp housing while forming a flow path for discharging the water vapor from the interior of the lamp housing to the exterior, and large pore diameter structures having larger diameters than that of the small pore diameter structures and being provided in such a manner as to communicate with the small pore diameter structures. The above allow for the provision of an aeration member and an aeration device that can promote the transfer of water vapor between the interior and the exterior of the housing.

Abstract: A ventilation component (1a) includes a supporting portion (10), a gas-permeable membrane (20), and a sealing member (30). The supporting portion (10) has a ventilation path (12) and an annular surface (14). When the ventilation component (1a) is attached to a housing (2), the ventilation path (12) extends in a direction perpendicular to an opening plane of an opening (2a), and extends through the supporting portion (10). The annular surface (14) faces an outer surface (2e) of the housing (2), and surrounds the ventilation path (12) in plan view. The gas-permeable membrane (20) closes the ventilation path (12) in a ventilatable manner. The gas-permeable membrane (20) allows a gas to pass therethrough in a thickness direction of the gas-permeable membrane (20). The sealing member (30) is sandwiched between the outer surface (2e) of the housing (2) and the annular surface (14) to seal a gap between the outer surface (2e) of the housing (2) and the annular surface (14). The sealing member (30) includes at least one selected from the group consisting of a pressure-sensitive adhesive, an adhesive, and a cured product of an adhesive.
