Beschreibung
Zusammenfassung:	In the rotary compressor (1), the drive shaft (70) is configured such that it includes a lower eccentric portion (76), an auxiliary shaft portion (74), and a lower coupling portion (90) coupling them and satisfies ReL- eL< RS, wherein ReLis the radius of the lower eccentric portion (76), Rsis the radius of the auxiliary shaft portion (74), and eLis the eccentricity of the lower eccentric portion (76). Further, the lower coupling portion (90) is formed such that its outer surface does not extend out of the outer surface of the lower eccentric portion (76), and it is provided with a reinforcement portion (92) with its outer surface positioned outside the outer surface of the auxiliary shaft portion (74) in the radial direction of the drive shaft (70).
