    Abstract: A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.

    Abstract: A ventilation housing of the present disclosure includes: a housing; and a ventilation assembly. The housing includes a tubular projection extending to project from an outer surface and internally having a first space communicating the inside and the outside of the housing. The ventilation assembly includes: an internal member being a tubular body having an opening at a first end portion and an opening at a second end portion; a gas-permeable membrane covering the opening at the first end portion of the internal member; and an external member being a tubular body having a bottom, the external member being joined to the internal member with the internal member inserted in the interior of the external member from the first end portion side. The ventilation assembly is fixed to the projection with the projection inserted in the opening at the second end portion of the internal member to make an inner peripheral surface of the internal member and an outer peripheral surface of the projection abut each other. The ventilation assembly has a second space serving as a ventilation path connecting the gas-permeable membrane and the outside of the ventilation assembly in the inside of the internal member, the inside of the external member, and/or an interspace between the two members. A ratio between an area S1 of a cross-section of the first space and a smallest total area S2min determined by comparison of values of different total areas determined at different distances from the gas-permeable membrane, the total areas each being determined for a cross-section(s) of the second space, is 1.0 or more. A ratio between the area S1 and a total area S2out of a plane consisting of a cross-section(s) of the second space taken at a position(s) where the second space is the narrowest is more than 1.0. This ventilation housing exhibits excellent performance in terms of moisture permeation between the inside and the outside of the housing.

    Abstract: The ventilation unit includes: an explosion-proof valve that permits gas to flow from the inside of a housing to the outside of the housing when internal pressure within the housing is higher than external pressure outside the housing by a value larger than or equal to a predetermined value, and is capable of returning to block the flow of the gas from the inside of the housing to the outside of the housing; and a ventilation membrane that permits gas to flow between the inside and the outside of the housing even when a pressure difference between the internal pressure and the external pressure is less than the predetermined value.

    Abstract: A ventilation component 1a includes an internal member 10, a gas-permeable membrane 20, and an external member 30. The internal member 10 has an open tubular structure, and has a protruding portion 11 on an outer circumferential surface of the open tubular structure. The gas-permeable membrane 20 covers one opening of the internal member 10. The external member 10 is formed to have a closed tubular structure and has a hooking portion on an inner circumferential surface of the closed tubular structure, the hooking portion hooking the protruding portion. The internal member 10 is fixed to the external member 30 in a state where the internal member 10 is inserted inside the external member 30 and the external member 30 hooks the protruding portion 11 by the hooking portion 33. The ventilation component 1a is capable of being fixed to a projection 2p tubularly protruding from an outer surface of a housing 2. When the internal member 10 and the external member 30 are viewed in plan along an axis A, the ventilation component 1a satisfies a requirement IH

The ventilation assembly includes: an internal member being a tubular body having an opening at a first end portion and an opening at a second end portion; a gas-permeable membrane covering the opening at the first end portion of the internal member; and an external member being a tubular body having a bottom, the external member being joined to the internal member with the internal member inserted in the interior of the external member from the first end portion side. The ventilation assembly is fixed to the projection with the projection inserted in the opening at the second end portion of the internal member to make an inner peripheral surface of the internal member and an outer peripheral surface of the projection abut each other. The ventilation assembly has a second space serving as a ventilation path connecting the gas-permeable membrane and the outside of the ventilation assembly in the inside of the internal member, the inside of the external member, and/or an interspace between the internal member and the external member joined together. A height H1 of the internal member is 6 to 10 mm. A ratio of the height H1 of the internal member to a height H2 of the projection is 1.00 to 1.70. The ventilation housing of the present disclosure exhibits excellent performance in terms of moisture permeation between the inside and the outside of the housing and is capable of reducing dropping of the ventilation assembly from the projection of the housing.

    Abstract: A housing kit (90) includes a housing body (20) and a ventilation member (10). The housing body (20) has a vent hole (21). The ventilation member (10) has a leg portion (26). The leg portion (26) is a portion adapted to be inserted into the vent hole (21). The housing body (20) has an inner peripheral surface (23) that defines the vent hole (21). The inner peripheral surface (23) includes a first rounded segment (23R1), a first straight segment (23S1),ounded segment (23R2), and a second straight segment (23S2) that are formed in order from an exterior space (24) side to an interior space (22) side of the housing body (20). The first rounded segment (23R1) and the second rounded segment (23R2) each form a curve convex toward a central axis (O) of the vent hole (21) in a cross section of the housing body (20) including the central axis (O). The first straight segment (23S1) and the second straight segment (23S2) each form a straight line in this cross section.
