Abstract
An exhaust purifying device for reducing toxic components contained in an exhaust emanating from an internal combustion engine. The device has a casing connected at both ends thereof to an exhaust system extending from the engine, and a core received in the casing and provided with a honeycomb structure constituted by a corrugated sheet and a flat sheet which are rolled up together in a spiral configuration. A pair of retaining members are received in axially opposite ends of the casing for preventing the core from moving in the axial direction and circumferential direction relative to the casing. Each of the retaining members radially traverses the associated end of the casing and includes a biting portion slightly biting into the associated end of the core.
