PROBLEM TO BE SOLVED: To provide a vehicle exhaust emission control device having a mechanism for preventing the deterioration of an exhaust gas purifying catalyzer in the vehicle exhaust gas purifying device which can be used on the test line of a maintenance workshop or the like, and directly catch and purify the exhaust gas per vehicle, and discharges it into an outside environment. SOLUTION: In an exhaust gas introduced from an exhaust gas catching nozzle detachably attached to a vehicle exhaust pipe and an introducing port C into the inside of a device body, a carbonaceous particle and an unburnt fuel component are removed in a filter chamber 10, and then HC, NOx and CO being main component of the exhaust gas are removed in a catalyzer chamber 20. The filter chamber 10 has a filter chamber 11 and an electric dust catching section 12. The unburnt fuel component adsorbed by the electric dust catching section 12 is separated in a cleaning chamber 40 to enable the electric dust catching section to be used again. |
