摘要

The device (1) has a housing (2) comprising a jacket (6) and an outlet funnel (8). An exhaust gas treatment element (3) is arranged in the jacket and axially supported at the housing via a support ring (11). The outlet funnel comprises an outer funnel (12) connected to the jacket in a fixed manner, and an inner funnel (13) carrying the support ring. An insulation space (14) is formed between the inner and outer funnels, and envelopes the inner funnel in a circumferential direction, where an inner end of the inner funnel bears against an inner end of the outer funnel facing the jacket.
