PROBLEM TO BE SOLVED: To prevent inconveniences such as thermolysis of working fluid due to an increase in temperature of the working fluid and carbonization of contained oil by removing preheat of a heat exchanger 15 for exhaust gas by working fluid of a Rankine cycle without power supply after an operation stop of an engine. SOLUTION: In this operation stop method for a waste heat regeneration device, an expander 12 expands overheated vapor of the working fluid generated in a second heat exchanger 15 in iso-entropy to take out the vapor as power of the engine 1. When stopping the operation of the engine 1, an electromagnetic clutch 19 is intercepted while the working fluid is circulated in a Rankine cycle circuit 10 and a pump integral type expander 13 is independently operated.
