Abstract
A vent member () includes a support body () provided with a through-hole (), a permeable membrane () closing the through-hole () in the support body (), and a cover part () covering the permeable membrane (). A ventilation hole () is made in a ceiling portion () of the cover part () and a notch () is made in a side wall portion () thereof. These ventilation hole () and notch () function as a passage for ventilation between the interior and the exterior of the cover part (). The ventilation hole () establishes a positional relation that it does not overlap a permeable region of the permeable membrane () in the axial direction. Further, the side wall portion () extends to the lower side in the axial direction below a position at which the permeable membrane () is disposed, and the permeable membrane () is protected entirely along a circumferential direction by the side wall portion (). The permeable membrane () is disposed on a mesa-like portion () that is convex to the upper side in the axial direction.
