Abstract:
A casing kit (1a) is provided with: a casing (10); and a ventilation member (20). The ventilation member (20) is disposed at an opening (12), and is attached to the casing (10). The ventilation member (20) is provided with a ventilation film (22), a support (24), and a sealing member (26). The sealing member (26) seals a gap between the support (24) and the casing (10) at the opening (12). The casing (10) has a flat surface (11f) and a tapered surface (11t). The tapered surface (11t) provides the opening (12), the diameter of which reduces toward the internal space of the casing (10).
