A variable displacement compressor is provided with a displacement control valve mechanism (93). This displacement control valve mechanism includes a pressure chamber (127) defined from a valve chamber (97), a second passage (89) leading to the pressure chamber and a crank chamber (29), and a valve guide portion (119) which supports a valve body (117) while allowing the valve body inserted therein. This displacement control valve mechanism has one end of the valve body exposed to the pressure chamber, its pressure receiving area being Sc. The variation in the characteristics of this displacement control valve mechanism can be realized by the alteration in Sc, which alteration is practically easy.
