Abstract:

A vent member (1) has a support body (2) having a through-hole (3) formed in it; a vent film (6) for closing the through-hole (3) of the support body (2); and a cover part (10) for covering the vent film (6). A vent hole (10a) is formed in a ceiling section (11) of the cover part (10), and a cutout (10b) is provided in a side wall section (12). The vent hole (10a) and the cutout (10b) function as the route for ventilation between the inside and outside of the cover part (10). The vent hole (10a) is positioned so that it is not superposed on the vent region of the vent film (6). Further, the side wall section (12) of the cover part (10) extends up to a position axially below the position where the vent film (6) is placed, protecting the circumferentially entire region of vent film (6). The vent film (6) is placed on a tableland-like section (14) projecting axially upward.
