A piping structure for a refrigerant cycle device includes an inner heat exchanger, and a bypass pipe through which refrigerant flows while bypassing the inner heat exchanger. The inner heat exchanger has a first flow passage in which high-pressure refrigerant before being decompressed flows and a second flow passage in which low-pressure refrigerant after being decompressed flows. The refrigerant cycle device includes plural low-pressure side heat exchangers, and the plural low-pressure side heat exchangers are located such that refrigerant from a part of the low-pressure side heat exchangers flows through the second flow passage of the inner heat exchanger, and refrigerant from the other part of the low-pressure side heat exchangers flows through the bypass pipe while bypassing the inner heat exchanger.
