PROBLEM TO BE SOLVED: To provide a ranking cycle device provided with an expander and a pump which are lubricated with lubricating oil, separately collecting the lubricating oil mixed into working fluid in the expander and pump and supplying the appropriate amount of lubricating oil to the expander and pump. SOLUTION: This ranking cycle device 10 includes: a working fluid circulating circuit 20 formed by sequentially connecting a force feeding pump 2 forcibly feeding the working fluid, heaters (a regenerative heat exchanger 16 and an evaporator 5), the expander 1 and a condenser 6 through channels; an oil separator 11 separating the lubricating oil mixed into the working fluid in the expander 1 and force feeding pump 2 from the working fluid; an oil reservoir tank 12 reserving the lubricating oil; a first lubricating oil supplying passage 31 supplying the lubricating oil from the oil reservoir tank 12 to the expander 1; and a second lubricating oil supplying passage 32 supplying the lubricating oil from the oil reservoir tank 12 to the force feeding pump 2.
