Abstract
A housing has a heat exchange flow passage which branches from the main exhaust gas flow passage and converges to the main exhaust gas flow passage through the heat exchanger. The valve has a valve pipe constituting the main exhaust gas flow passage in the exhaust pipe and a valve body which rotates to contact a seat part downstream of the valve pipe in an exhaust gas flow direction such that the exhaust gas flows to the heat exchange flow passage. An out port of the heat exchange flow passage which converges to the main exhaust gas flow passage is disposed upstream of a downstream side distal end of the valve pipe in the exhaust gas flow direction, and the downstream side distal end of the valve pipe in the exhaust gas flow direction is disposed upstream of a downstream side distal end of the heat exchanger in the exhaust gas flow direction.
