ABSTRACT:
An exhaust gas cleaning device is constructed of a metal casing and a honeycomb core body fixedly inserted in the metal casing. The honeycomb core body have 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 relation, defines a number of network-patterned axial gas flow passages, and is adapted to carry an exhaust gas cleaning catalyst thereon. The metal casing defines a cavity compartment isolated from an exterior. Preferably, at least one rib or partition wall is arranged in the cavity compartment of the metal casing.
