PROBLEM TO BE SOLVED: To apply the same counterweights to plural types of compressors. SOLUTION: A counterweight 23 installed on an eccentric bush has plural weight members 23a-23c fixed to a base weight member 23d by a coupling member 50, at least one of the weight members 23a-23c has a housing part 61 in a part including the coupling member 50, and the housing part 61 is combined with an auxiliary weight member 71 movably shaft-supported on the coupling member 50 to be capable of overhanging from the housing part 61 over a circumferential edge.
