Abstract

Windbreak cover is provided on the periphery of both heater and the air introducing pipe through which heated air is permitted to flow. The windbreak cover blocks the wind from blowing against the heater and the air introducing pipe while the vehicle is running. Since neither the heater nor the air introducing pipe is cooled with the wind that blows while the vehicle is running, the temperature of the heated air that is introduced into the exhaust pipe will not drop even when the vehicle is running. As a result, the temperature of the air being introduced can be maintained at a predetermined level, thus permitting the exhaust gas to be purified in consistent manner.
