Patent ID: 8540940

Claim:
A catalytic converter device comprising: a catalyst carrier that carries a catalyst for purifying exhaust gas exhausted from an internal combustion engine and is heated by passing an electric current therethrough; a cylinder that is formed in a cylindrical shape, contains the catalyst carrier inside, and is attached to an exhaust pipe; a holding member that is equipped with an inside elastic member placed on an outer peripheral surface side of the catalyst carrier, an outside elastic member placed on an inner peripheral surface side of the cylinder, and a middle member placed between the inside elastic member and the outside elastic member, with the holding member holding the catalyst carrier in the cylinder by the elasticity of the inside elastic member and the outside elastic member and electrically insulating the catalyst carrier and the cylinder; a projecting portion that is disposed on at least part of an upstream-side end portion of the middle member in a flow direction of the exhaust gas and is positioned on the upstream side of an upstream-side end portion of the outside elastic member, and an insulating coating layer that is placed between the catalyst carrier and the inside elastic member and electrically insulates the catalyst carrier and the inside elastic member.
