2-cylinder rotary compressor

PROBLEM TO BE SOLVED: To provide a two-cylinder rotary compressor improving assemblability while ensuring the reliability of a crankshaft, and achieving high output and high efficiency. SOLUTION: This two-cylinder rotary compressor includes in a sealed vessel: an electric motor having a stator and a rotor; the crankshaft having a main shaft driven with the electric motor and fixed to the rotor; an auxiliary shaft provided on a side opposite to the main shaft in an axial direction; an eccentric part on the side of the main shaft and an eccentric part on the side of the auxiliary shaft which are formed by having a phase difference of approximately 180° between the main shaft and auxiliary shaft; and an intermediate shaft provided between the eccentric part on the side of the main shaft and the eccentric part on the side of the auxiliary shaft. The shape of the intermediate shaft is formed to project in the direction perpendicular to the eccentric directions of the eccentric part on the side of the main shaft and eccentric part on the side of the auxiliary shaft.
