Abstract
An air-permeable water non-permeable device includes a unit including a rubber outer case, a rubber inner case, and an air-permeable water non-permeable sheet sandwiched therebetween; and a housing. The inner case is fitted inside a cylindrical portion of the outer case, the air-permeable water non-permeable sheet being sandwiched between a through-holed base portion of the outer case and a through-holed cylindrical body of the inner case. The through-holed base portion of the outer case faces a mounting through-hole of the housing and the retainer flange portion is externally orientated. The outer case is provided with an insertion guidance small-diameter portion which is not compressed by the retainer inner cylindrical surface and is smaller in diameter than the retainer inner cylindrical surface, and a retainer large-diameter portion which is compressed by the retainer inner cylindrical surface and is larger in diameter than the retainer inner cylindrical surface.
