A displacement control valve () is connected to a variable displacement compressor. An open passage () in which a refrigerant gas flows is formed within a rod () and a valve body () of the displacement control valve (). Further, an inner circumferential surface of a valve chamber () is formed as a guide portion () for moving the valve body () along an axis (L) of the valve chamber (). A valve portion () of the valve body () is formed in a circular arc cross sectional shape along a surface of a sphere (K) in which an intermediate point of a length of the guide portion () along the axis (L) of the valve chamber () is set to a center (N) on the axis (L), and a distance from the center (N) to a contact point between a valve seat () and the valve portion () is set to a radius (r).
