Claims

[Claims for Utility Model Registration] An inner passage member forming a first exhaust gas passage; and an outer passage provided on the outer periphery of the inner passage member and forming a second exhaust gas passage on the outer periphery of the inner passage member. and a heat transfer medium passage provided in contact with the second exhaust gas passage, between the exhaust gas passing through the second exhaust gas passage and the heat transfer medium passing through the heat transfer medium passage. In the exhaust heat exchanger that performs heat exchange, an inner valve consisting of two halves for opening and closing the first exhaust passage is provided in the first exhaust passage, and the two halves of the inner valve An exhaust heat exchanger characterized in that two halves of an outer valve for opening and closing the second exhaust passage are fixed to respective rotation shafts so as to be substantially perpendicular to the half of the inner valve.
