the displacement control valve being characterized in that the drive rod is fitted to the shaft passage and coupled to the valve body structure so as to form a gap passage (67, 68, 67A, 68A, 67B, 68B, 67C, 68C) between an outer surface of the drive rod and a wall surface of the shaft passage; the outer surface of the drive rod includes a circumferential surface and a retracted surface (652, 653, 655) located inward from a hypothetical circumferential surface having the same diameter as the circumferential surface; and the gap passage (67, 68, 67A, 68A, 67C, 68C) is formed between the wall surface of the shaft passage and the retracted surface (652, 653, 654). an electromagnetic solenoid; a drive force transmission body driven by the electromagnetic solenoid; a pressure sensitive chamber which is in communication with the control pressure chamber; a pressure sensitive unit (43, 45, 58) including a pressure sensitive body (55, 56) arranged in the pressure sensitive chamber; an internal passage (66, 67, 68, 67A, 68A, 67B, 68B, 67c, 68c, 491, 501) arranged in the drive force transmission body which is communicable with the pressure sensitive chamber; a first valve body arranged in the drive force transmission body to adjust the cross-sectional area of a passage between the suction pressure region and the internal passage (66, 67, 68, 67A, 68A, 67B, 68B, 67c, 68c 491, 501); a second valve body contacted with and separated from the pressure sensitive body (55, 56) and arranged in the drive force transmission body to adjust the cross-sectional area of a passage between the internal passage (66, 67, 68, 67A, 68A, 67B, 68B, 67c, 68c 491, 501) and the pressure sensitive chamber; and a third valve body arranged in the drive force transmission body to adjust the cross-sectional area of a passage between the pressure sensitive chamber and the discharge pressure region; wherein the first valve body includes an annular seal which is contactable with a valve seat surface facing toward the first valve body; the drive force transmission body includes a drive rod and a valve body structure having a shaft passage and forming the first valve body; the internal passage (66, 67, 68, 67A, 68A, 67B, 68B, 67C, 68C, 491, 501) includes a recess arranged radially inward from the annular seal, the shaft passage, and the gap passage (67, 68, 67A, 68A, 678, 688, 67C, 68C);
