ABSTRACT:
An exhaust gas cleaning device for a motor vehicle is constructed of a honeycomb core body 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 and then rolling the thus-superposed bands into a multi-layered spiral form with at least one outermost layer thereof being formed of the planar band. 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 honeycomb core body.
