Abstract
A compressor has a cylinder chamber (24) placed in a casing (1) and compressing refrigerant, a roller (29) for compressing the refrigerant in the cylinder chamber (24), a drive shaft (4) for driving the roller (29), a motor (3) for driving the drive shaft (4) and having a rotor (31) and a stator (32), and balance weights (31A, 31B) mounted on the rotor (31), spaced in the direction of the axis of the drive shaft (4). The drive shaft (4) has a first portion (41) on which the rotor (31) is mounted and a second portion (42) located nearer the cylinder chamber (24) than the first portion (41). The balance weight (31A) is located farther from the cylinder chamber (24) than the balance weight (31B). The center axis (S1) of the first portion (41) of the drive shaft (4) is offset relative to the center axis (S2) of the second portion (42) of the drive shaft (4) to the side opposite the side where the balance weight (31A) is placed.
