PROBLEM TO BE SOLVED: To provide a small-size solenoid valve device. SOLUTION: A yoke 12, a storage member 14, a suction portion 22 and a movable core 30 are formed of magnetic materials to form a magnetic circuit. A cylindrical opposite recessed portion 24 is formed in the suction portion 22 at the side end of the movable core 30. The movable core 30 is reciprocatingly supported on the inner periphery side face of the storage member 14. A side gap formed by the inner periphery side face of the storage member and the outer periphery side face of the movable core 30 is set large enough to allow the movable core 30 to be inclined to an axis 90 extending along the reciprocating direction of the movable core 30 by an axial shift between the storage member 14 and the suction portion 22. When the axial shift occurs between the storage member 14 and the suction portion 22, the movable core 30 is inclined to the axis 90 with an abutment position between a conical recessed face 32 and a spherical face 42 as a supporting position. A gap between the inner periphery side face 26 of the opposite recessed portion 24 and the movable core 30 has almost no change all over the periphery. COPYRIGHT: (C)2003,JPO
