A capacity control valve for controlling a flow rate or pressure according to a valve opening degree of a valve section, comprising: a valve main body having an interior space communicating with a third communication passage through which a fluid at a control pressure passes, a second valve chamber communicating with a second communication passage through which a fluid at discharge pressure passes and having a valve hole communicating with the interior space and a second valve seat arranged in the valve hole, and a first valve chamber communicating with a first communication passage through which a fluid at a suction pressure passes and having a first valve seat; a valve body (21; 41; 51) having an intermediate communication passage communicating with the interior space and the first communication passage, a second valve part (21b1) for opening and closing the valve hole by separating from and making contact with the second valve seat, a first valve part (21c1) which performs opening/closing action in reverse association with the second valve part (21b1) and which opens and closes communication between the intermediate communication passage and the first communication passage by separating from and making contact with the first valve seat, a third shaft part (21a; 41a; 51a) arranged in the interior space, and an auxiliary communication part (21f; 41f) which is arranged in the third shaft part (21a; 41a; 51a) and which allows communication between the interior space and the intermediate communication passage; a pressure-sensitive body which is arranged in the interior space and extends and contracts in response to the pressure of the interior space and which has a free end part sliding with the third shaft part (21a; 41a; 51a) of the valve body (21; 41; 51); and a solenoid section which is mounted to the valve main body and actuates the valve body (21; 41; 51) to opening/closing direction according to current, characterized in that the free end part is provided with a hole part (22c1) which is relatively slidably fitted to an end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a), a fitting length of the end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a) and the free end part of the pressure-sensitive body is set larger than a displacement amount of the free end part of the pressure-sensitive body by the pressure in the interior space, and the end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a) is provided with a groove part or an opening hole (41j; 51j). a valve main body having an interior space communicating with a third communication passage through which a fluid at a control pressure passes, a second valve chamber communicating with a second communication passage through which a fluid at discharge pressure passes and having a valve hole communicating with the interior space and a second valve seat arranged in the valve hole, and a first valve chamber communicating with a first communication passage through which a fluid at a suction pressure passes and having a first valve seat; a valve body (21; 41; 51) having an intermediate communication passage communicating with the interior space and the first communication passage, a second valve part (21b1) for opening and closing the valve hole by separating from and making contact with the second valve seat, a first valve part (21c1) which performs opening/closing action in reverse association with the second valve part (21b1) and which opens and closes communication between the intermediate communication passage and the first communication passage by separating from and making contact with the first valve seat, a third shaft part (21a; 41a; 51a) arranged in the interior space, and an auxiliary communication part (21f; 41f) which is arranged in the third shaft part (21a; 41a; 51a) and which allows communication between the interior space and the intermediate communication passage; a pressure-sensitive body which is arranged in the interior space and extends and contracts in response to the pressure of the interior space and which has a free end part sliding with the third shaft part (21a; 41a; 51a) of the valve body (21; 41; 51); and a solenoid section which is mounted to the valve main body and actuates the valve body (21; 41; 51) to opening/closing direction according to current, characterized in that the free end part is provided with a hole part (22c1) which is relatively slidably fitted to an end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a), a fitting length of the end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a) and the free end part of the pressure-sensitive body is set larger than a displacement amount of the free end part of the pressure-sensitive body by the pressure in the interior space, and the end part (21a1; 41a1; 51a1) of the third shaft part (21a; 41a; 51a) is provided with a groove part or an opening hole (41j; 51j).
