A capacity control valve includes a solenoid portion; a tube placed in the solenoid portion; and a movable core which forms a slide surface that is fitted to the tube. An actuation rod has a joint portion and a valve body, the joint portion being engaged with an abutting surface of a solenoid rod portion, and the valve body opening or closing a control fluid passage. The joint surface of the solenoid rod portion or the abutting face of the actuation rod has a concave cone-shape surface while the other has a convex cone-shape portion. A bottom face of the concave cone-shape surface is formed as a wide area of either a planar surface or a circular cross section, wherein a head portion of the convex cone-shape portion is truncated to form a truncated cone surface, the truncated cone surface corresponding to the bottom face of the concave cone-shape surface. |
