は、このような問題に対処することにある。By the way, in the metal carrier of this type, the inside of the honeycomb structure is exposed to high-temperature exhaust gas, and at the same time, reaction heat is generated due to a chemical reaction of polluting components in the exhaust gas. Since the heat accumulated in the honeycomb structure is radiated to the outside air through the outer cylinder, the honeycomb structure has a temperature distribution in which the temperature is higher toward the center and gradually lower toward the outer periphery. This temperature distribution causes a difference in expansion and contraction between the honeycomb structure and the outer cylinder. The intermediate cylinder functions to reduce the difference between the expansion and contraction. However, when expansion and contraction between the honeycomb structure and the outer cylinder repeatedly occur, the outermost periphery of the honeycomb structure is transmitted due to transmission of vibration from the vehicle and the like. Deformation or metal fatigue occurs in the outer foil plate or the intermediate cylinder forming the honeycomb structure, and finally, the honeycomb structure may be detached from the outer cylinder. Accordingly, it is an object of the present invention to address such problems.
