摘要

The equipment has a diaphragm (6) connected with a catalyst body (4) such that a support mat (5) is protected from a volume of material formed by an exhaust funnel (2). An outer circumference of the diaphragm is welded with an inner wall of the funnel or a tubular shell (3) so that an inner circumference of the diaphragm lies on an outer edge of a face side of the mat and is overlappingly placed with an outer periphery of the body.
