Abstract
A water-tight plastic component, with a ventilation opening for air exchange between the component interior and the component exterior, and with a gas permeable membrane that covers the ventilation opening to prevent the entry of water into the component interior. The membrane is inserted in a cup-shaped recess disposed in front of the mouth of the ventilation opening, and is clamped at the edge, together with a sealing ring, against the bottom of the recess, in order to achieve a simple assembly. The sealing ring and membrane edge are overlapped by segment tabs that are disposed axially spaced from the bottom of the recess and protrude radially from the cylinder wall of the recess, forming an undercut.
