徴とする空気流量制御弁。[Claims for Utility Model Registration] A plunger axially opposed to a housing fixed core provided with an air inlet and an air outlet is advanced by a compression spring, and the plunger is retracted by energization of an electromagnetic coil. The solenoid is airtightly connected to a housing, and the solenoid is made of a synthetic resin molded product, which is fixed to the front end of the solenoid, and the outer periphery of the solenoid is surrounded by a cylindrical part with a plurality of openings in the circumferential direction with a small gap. In the air flow control valve, the valve sleeve is configured to close an opening when the plunger moves forward, and to open the opening when the plunger retreats to allow air to flow from the air inlet to the air outlet. An air flow control valve characterized in that an inner peripheral portion is provided with a recess extending axially from one end at a position between the openings.
