PROBLEM TO BE SOLVED: To improve the aseismatic strength of an exhaust heat exchanger and an exhaust circulating component, in a heat exchanging device for exhaust in which the exhaust circulating component is connected with the exhaust heat exchanger.SOLUTION: A heat exchanging device for exhaust is equipped with an EGR cooler 100 performing heat exchange between exhaust and cooling water of an engine 1. In the EGR cooler 100, exhaust circulates, and an EGR valve 4 communicating with the EGR cooler 100 is connected to the EGR cooler 100. The EGR cooler 100 and the EGR valve 4 are coupled so as to relatively move the EGR cooler 100 to the EGR valve 4. The EGR cooler 100 is fixed to an engine 1 through a first bracket portion 61, and the EGR valve 4 is fixed to the engine 1 through a second bracket portion 62. The first bracket portion 61 and the second bracket portion 62 are integrally formed over a coupling portion 7 between the EGR cooler 100 and the EGR valve 4.SELECTED DRAWING: Figure 2 |
