PROBLEM TO BE SOLVED: To prevent high voltage wiring from being removed due to displacement, etc. caused by vibration of an exhaust pipe when an exhaust emission control device is connected to a high voltage power source, and to prevent heat from being transferred to a covered part made of synthetic resin of the high voltage wiring due to high temperature. SOLUTION: To connect a corona discharge electrode 2 of the exhaust emission control device 1 to the high voltage wiring 4, an electrode side terminal 22 is electrically connected to the high voltage wiring 4 by a coil spring 7 with flexible structure, and the corona discharge electrode 2 is connected to a connection end part of the high voltage wiring 4 with water resistance by a metal bellows 8, having the flexible structure, for covering its periphery. A cylindrical insulating member 9 made of rubber for electrically disconnecting the coil spring 7 and the bellows 8 without impairing flexibility thereof is interposed between the coil spring 7 and the bellows 8.
