PURPOSE:To minimize the couple unbalance moment to obtain stable running condition with less vibration by arranging a balance weight in the closest proximity of a movable scroll member. CONSTITUTION:A balance weight 271' is bonded to the side of a bush 27 by means of press in and the like, a balance weight 271'' being made integrally to the movable scroll member 21 side of said balance weight 271', and said balance weight 271'' being extended into a aproximately triangle shaped space formed between a fixed race 221, fixed ring 222 and a boss 213 due to the circular movement of the movable scroll member 21 and the eccentric movement of the boss thereby providing sufficient eccentric weight. |
