Summary:To simplify the manufacture of a rotor and miniaturize a compressor while easily keeping a balance between the rotor and the eccentric part of a crankshaft. A rotor (52A) comprises a body (521) and a balance weight (71). The body (521) is provided with a through-hole (521a) that extends through the body along the direction (91). The body (521) includes steel plates (5211) laminated in the direction (91). The balance weight (71) is inserted into the through-hole (521a). The length (L71) of the balance weight (71) in the direction (91) is shorter than the length (L521a) of the through-hole (521a) into which the balance weight (71) is inserted. Cette invention a pour objet de simplifier la fabrication d'un rotor et de miniaturiser un compresseur tout en maintenant facilement un équilibre entre le rotor et la partie excentrée d'un vilebrequin. Un rotor (52A) comprend un corps (521) et un contrepoids (71). Le corps (521) est doté d'un trou débouchant (521a) qui s'étend à travers le corps le long de la direction (91). Le corps (521) comprend des plaques d'acier (5211) laminées dans la direction (91). Le contrepoids (71) est inséré dans le trou débouchant (521a). La longueur (L71) du contrepoids (71) dans la direction (91) est plus courte que la longueur (L521a) du trou débouchant (521a) dans lequel est inséré le contrepoids (71).
