<P>PROBLEM TO BE SOLVED: To provide a flap-type solenoid-driven valve capable of satisfactorily bringing a core and a disk into close contact with each other irrespective of a tolerance of assembly of component parts. Ž<P>SOLUTION: The flap-type solenoid-driven valve includes the disk 11 made of a magnetic material and pivotally supported in a swingable manner, and an upper core 16 and a lower core 17 which are core members of electromagnets for generating electromagnetic force that attracts the disk 11. The flap-type solenoid-driven valve drives a valve element 20 for opening/closing the same by swinging movement of the disk 11 caused by the cooperation of the electromagnetic force and spring force. In the flap-type solenoid-driven valve, a swing shaft of the disk 11 is supported by a fluid sealed bearing 14 in a floating state and an alignment member 28 is integrally secured to the upper core 16/the lower core 17. The alignment member 28 has a V-shaped groove 27 for making sliding contact with circular pins 26 projectingly formed on each side face of the disk 11 so as to guide the disk 11 to a predetermined position as the disk 11 comes closer to the upper core 16/the lower core 17, thereby axially aligning the swing shaft of the disk 11.
