Claims (1)

[Scope of utility model registration request] A particulate waste trap is disposed in the exhaust passage of an internal combustion engine, and a heater installed opposite to the inflow end of the particulate particulate trap burns the particulate on the particulate particulate trap to perform regeneration processing. An exhaust gas after-treatment device characterized in that the heater is connected to a power circuit on the outside of the vehicle through a joint portion that connects each wiring on the vehicle side and the outside of the vehicle.
