The present invention provides a rotary compressor (100), which enables the eccentricity of an eccentric shaft part (51a, 51b) of a crankshaft (50) to be increased in order to increase the maximum volume of a compression chamber, wherein the assembly will not be deteriorated, the leakage of the refrigerants will be prevented, and the compression efficiency can be improved. The rotary compressor drives a pair of compression mechanism parts (10a, 10b) superposed across a partition plate (30) by utilizing a crankshaft (50) with two eccentric shaft parts (51a, 51b); the crankshaft (50) is provided with shaft parts (52a, 52b), which are supported by end plates on two sides, and are formed with different outer diameters; eccentric shaft parts (51a, 51b) of the crankshaft (50) are formed with different outer diameters; the inner diameter of a central through hole (33) of the partition plate (30) is less than any of the outer diameters of the eccentric shaft parts (51a, 51b) of the crankshaft (50), and the partition plate (30) is segmented so as to surround a partition plate insertion part (53) of the crankshaft (50). |
