タ。[Claims for Utility Model Registration] (1) A cylindrical portion that accommodates a core portion on which a catalyst for purifying exhaust gas is supported, and an inlet portion to which an exhaust inflow pipe is connected are connected to the cylindrical portion. In a catalytic converter connected by a diameter-enlarging portion that gradually increases in diameter toward the side, an internal space formed by the diameter-increasing portion is divided by a flow divider plate, and the exhaust gas is directed to the core portion by the flow divider plate. A catalytic converter characterized by forming a plurality of diffusion protrusions that diffuse outward from the center of the converter. (2) The diffusion protrusion includes a first protrusion that is formed at the exhaust gas inlet of the flow divider plate, protruding into the exhaust gas passage and spanning almost the width of the inlet of the flow divider plate, and a first protrusion formed on the downstream side of the first protrusion. The catalytic converter according to claim 1, which is a registered utility model, comprising: a second protrusion divided into a plurality of parts in a direction perpendicular to the exhaust gas inflow direction; (3) The catalytic converter according to claim 1 or 2, wherein the core portion is made of a metal honeycomb catalyst carrier or a ceramic catalyst carrier.
