Abstract

A device for exposing an opening in a housing part of a steering gear in a vehicle steering system has a closure element that closes the opening and a component that, when it comes into contact with a liquid, changes at least one of its properties such that, after the component cooperates with the closure element, the closure element exposes the opening.
