PROBLEM TO BE SOLVED: To provide a solenoid valve device surely suppressing the rotation of an armature electromagnetically driving the opening/closing of a valve element of a valve of, for example, an internal combustion engine in a simple constitution. SOLUTION: This solenoid valve device disposed as the valve for the internal combustion engine is so constituted as to store the armature 24 and electromagnets 22 and 23 attracting it in the upper part and the lower part in a housing 27. The armature 24 is integrally formed of an armature stem 29, supported thereby and reciprocates based on the attraction force by the electromagnets 22 and 23. The valve element 21 opens/closes a suction port 11 by connected to the armature stem 29. The armature 24 has a rectangular planar shape. A guide shaft 33 guiding the reciprocating motion of the armature 24 penetrates through a part adjacent to the longitudinal end part of the armature 24. COPYRIGHT: (C)2004,JPO
