Abstract

The invention relates to a static mixer for an exhaust gas system of an internal combustion engine-driven vehicle, with a plurality of flow guide elements which influence the flow of an exhaust gas stream and which are inclined at a given angle relative to the mixer plane and are held in the exhaust gas channel by means of at least one retaining strip. According to the invention the at least one retaining strip is made resilient at least in partial regions and/or is elastically supported in the plane of the mixer.
