Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exhaust emission control device allowing a driver to cancel at his/her judgement the regenerating control of a particulate filter during idling. SOLUTION: The exhaust emission control device comprises the catalyst regenerative particulate filter 6 mounted on the way of an exhaust pipe 4 and a fuel adding means (a fuel injection device 10) provided on the upstream side of the particulate filter 6 for adding fuel into exhaust gas 3. The fuel adding means adds the fuel thereinto when the need exists for burning and removing trapped particulates to regenerate the particulate filter 6, and regenerating control is executed to increase an idling speed to be higher than usual one only during adding the fuel in an idling condition. A manual canceling means (an idle volume 14) is provided for selectively canceling the regenerating control of the particulate filter 6 with manual operation only during idling.
