<p>A plastic casing (11) used e.g. in a motor vehicle windscreen wiper assembly, is a single- or multi-part arrangement having, in one section a vent opening (16) for air exchange between the interior and the surroundings. Covering the opening (16) is a gas-permeable membrane (17), which prevents water entering, with enclosure of its periphery achieved by using the plastic material in the casing.</p> |
