The purpose of the present invention is to provide a low-cost heat cycle system that can reduce power consumption; an in-wheel motor that is driven by using this heat cycle system; and a vehicle in which this heat cycle system is installed. This heat cycle system is provided with: a compressor; an accumulator; an electric drive unit comprising an electric motor; a refrigerant compressed by the compressor; and an indoor heat exchanger and an outdoor heat exchanger responsible for heat exchange of the refrigerant. The heat cycle system comprises a four-way valve that comprises a single circulation path for circulating the refrigerant and that can switch the connection destination of a refrigerant discharge section of the compressor to the indoor heat exchanger or the outdoor heat exchanger. A cooling unit of the electric drive unit is arranged upstream of the accumulator in the flow of the refrigerant.
