Summary:A venting unit for a housing has a base body to be connected fluid-tightly to a rim of a housing opening. The base body has a gas passage opening closed by a membrane that spans areally across the gas passage opening transversely to an axial direction. An actor is operatively connected to the base body and has an emergency venting spike extending axially toward the membrane. The emergency venting spike has a tip or a cutting edge arranged, in a state of rest, at a predetermined distance from a membrane surface of the membrane and can move toward the membrane when the actor is actuated so that tip or cutting edge punctures the membrane. A cover arranged at an outer side of the base body covers the gas passage opening. A fastening mechanism connects cover and base body. The actor has an actuation element for releasing the fastening mechanism.
