  • Catalytic converter and method for manufacturing casing
    Patent number: 10494973
    Abstract: A catalytic converter includes: a tubular casing including at least a pair of holding tubular parts and a reduced diameter tubular part that integrally connects the holding tubular parts to each other; and a monolithic catalyst carrier accommodated in each of the holding tubular parts, the reduced diameter tubular part being obtained by press-forming a portion, between the holding tubular parts, of a casing material of a tubular shape that corresponds to that of the holding tubular parts. Flat parts are formed respectively in a plurality of places at intervals in a peripheral direction of the reduced diameter tubular part, a sensor being attached to at least one of the flat parts. Accordingly, a press load when press-forming the reduced diameter tubular part is suppressed from becoming large and unequal in the peripheral direction of the reduced diameter tubular part.
