Capacity control valve

A capacity control valve in which a position of a valve element is changed by drawing a movable iron core to a fixed iron core with magnetic force generated in accordance with energization of an electromagnetic coil, wherein

• one of the fixed iron core and the movable iron core includes a projected portion which is projected in an axial direction on a side of an outer peripheral surface of the one of the fixed core and the movable iron core,
• a remaining one of the fixed iron core and the movable iron core includes a projected portion which is projected in the axial direction on a side of an inner peripheral surface of the remaining one of the fixed core and the movable iron core,
• the projected portions are capable of being loosely fitted to each other when the movable iron core is drawn to the fixed iron core,
• the projected portion of the one of the fixed iron core and the movable iron core is formed in a tapered shape so as to have, as a distal end surface thereof, an effective magnetic force surface which is smaller than an opposing surface of the remaining one of the fixed iron core and the movable iron core, the opposing surface facing the effective magnetic force surface;
• and
• the projected portion of the remaining one of the fixed iron core and the movable iron core is formed in a shape of equal width including a leading end surface which extends in a direction perpendicular to an axial direction and an outer peripheral surface which is continuous to the leading end surface and forms a surface parallel to the axial direction.
