PROBLEM TO BE SOLVED: To provide a waste heat recovery device to recover energy from the steam generated by the waste heat of engine, capable of recovering the energy efficiently in case the power recovery is resumed from the condition that power recovery can no more be conducted owing to a decrease of the steam amount generated. SOLUTION: The waste heat recovery device 1 is equipped with an impulse turbine 7 to work when the steam generated by the waste heat of the engine 100 is introduced, an electromagnetic clutch 10 to make coupling and uncoupling of a power shaft 73 of the turbine 7 with/from its rotor 12, and pulleys 13 and a belt 14 to transmit the power from the turbine 7 to a crank shaft 32 when the rotor 12 is coupled with the crank shaft 32 and the clutch 10 is coupled with the power shaft 73 and the rotor 12. The waste heat recovery device 1 has an ECU 17 which works when the steam amount introduced to the turbine 7 decrease below the first prescribed amount A1, for uncoupling the power shaft 73 from the rotor 23 using the clutch 10 while introducing the steam to the turbine 7 is continued.
