ABSTRACT:
An exhaust gas cleaning device is constructed of a honeycomb core body. The honeycomb core body is 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 planar band and corrugated band together into a multilayered spiral form, defines a number of network-patterned axial gas flow passages, and is further processed to carry an exhaust gas cleaning catalyst thereon. The honeycomb core body defines, along the central axis of rolling thereof, an open cylindrical hollow space of a diameter .phi..sub.2 satisfying the following formula: ##EQU1## wherein .phi..sub.1 is the outer diameter of the honeycomb core body, and
