PROBLEM TO BE SOLVED: To provide fluid machinery provided with a reliable lubrication-mechanism of a simple structure. SOLUTION: In the fluid machinery, a compressor (50), an expansion device (60), and an electric motor (40) are housed in one casing (31). The compressor (50), the expansion device (60), and the electric motor (40) are connected by one driving shaft (45). An oil pump (38) is provided to a shaft end (48) of the driving shaft (45). The oil pump (38) delivers the lubricating oil stored in the casing (31) to an oil-feeding path (47) in the driving shaft (45) to feed the oil to a bearing for the compressor (50) and the expansion device (60).
