ABSTRACT:
An exhaust gas cleaning device for a motor vehicle is constructed of a metal casing open at both ends thereof and a honeycomb core body fixedly enclosed within the metal casing. The honeycomb core body has been formed by superposing a planar band made of a metal sheet and a corrugated band made from another metal sheet one over the other in a contiguous relationship. The honeycomb core body defines a number of network-patterned axial gas flow passages and is adapted to carry an exhaust gas cleaning catalyst. At least one fin is fixed on an outer peripheral wall of the metal casing.
