description	PROBLEM TO BE SOLVED: To considerably reduce emission sound emitted from a catalyst cover by effectively reducing high frequency vibration transmitted from a catalyst case of a catalytic converter body to the catalyst cover, with vertical sliding friction generated by a friction holding means in holding structure for the catalyst cover for covering the catalytic converter body interposed in an exhaust system connected to an exhaust port of an engine, to clean the noxious components flowing in the exhaust system. SOLUTION: The friction holding means HF is provided between the catalyst case 21 of the catalytic converter body 20 and the catalyst cover 30. The friction holding means HF generates vertical sliding frictional force between the catalyst case 21 and the catalyst cover 30 to hold the catalyst cover 30 to the catalyst case 21 by the sliding frictional force.
