Title: Fitting structure for controlling valve in variable capacity compressor

Abstract: In a fitting structure of a control valve in a variable capacity compressor according to the present invention, a step portion 92 is formed by connecting two taper surfaces 93a and 93b, the diameter of each of which decreases progressively towards the depth of a fitting hole 32 (in an inserting direction of a control valve 33) between each step surface portion 57, 67, 74, 91 of a fitting hole 32. A first taper surface 93a at a deep part of each step portion 92 has a smaller inclination in the inserting direction than a second taper surface 93b on the inlet side. The first taper surface 93a is formed so that its inner diameter on the inlet side is a little greater than the outer diameter of each O-ring 61, 70, 77 disposed on each step surface portion 57, 67, 74 in a free condition.
