US 2022/0287191 A1 · VENTILATION STRUCTURE

Abstract

A ventilation structure (1a) includes a housing (10a) and a ventilation component (20a). The housing (10a) has a first surface (12) defining a lateral surface of a columnar space (11c) in an attachment hole (11). The ventilation component (20a) is attached to the housing (10a) to close the attachment hole (11). The ventilation component (20a) has a ventilation path (21) between an inner space (15u) of the housing (10a) and an outer space (15s) of the housing (10a). The ventilation component (20a) includes a supporting portion (23), a gas-permeable membrane (22), a protruding portion (24), and a sealing member (25). The supporting portion (23) surrounds the ventilation path (21) in plan view. The protruding portion (24) protrudes from the supporting portion (23) toward the inner space (15u) of the housing (10a), and is inserted into the attachment hole (11). The sealing member (25) is disposed on an outer periphery of the protruding portion (24), and seals a gap between the first surface (12) and the protruding portion (24).

Dependent claims

A ventilation structure comprising:

a housing having an attachment hole and a first surface, the first surface:
defining a lateral surface of a columnar space in the attachment hole;
or defining a taper in the attachment hole in which a hole diameter decreases in a direction from an inner space of the housing toward an outer space of the housing;
and
a ventilation component attached to the housing to close the attachment hole, and having a ventilation path between the inner space of the housing and the outer space of the housing, wherein
the ventilation component comprises:
a supporting portion being annular and surrounding the ventilation path in plan view;
a gas-permeable membrane closing the ventilation path in a ventilatable manner;
a protruding portion protruding from the supporting portion toward the inner space, and being inserted into the attachment hole to be in contact with the housing;
and
a sealing member disposed on an outer periphery of the protruding portion, and sealing a gap between the first surface and the protruding portion.
