PROBLEM TO BE SOLVED: To provide an exhaust heat recovery device improved in durability.SOLUTION: A second pipeline 22 branched from a first pipeline 14, in which an exhaust gas from an engine flows, is equipped with a heat recovering device 24. A valve member 18 of the first pipeline 14 for determining a displacement volume to flow in the second pipeline 22 is driven by a first actuator 40 and a second actuator 70. As a result, the individual driving frequencies of the first actuator 40 and the second actuator 70 are suppressed to improve the durability. |
