A solenoid device includes: a first electromagnetic coil; first and second plungers movable according to energization to the first electromagnetic coil; first and second fixed cores facing the first and second plungers, respectively; and a yoke. When the first electromagnetic coil is not energized, first and second gaps are formed between the first and second plungers and the first and second fixed cores, respectively. When the first electromagnetic coil is energized, the magnetic flux flows in a first magnetic circuit, provided by the first plunger, the first fixed core and the yoke, via the first gap, and a second magnetic circuit, provided by the first and second plungers, the first and second fixed cores and the yoke, via the first and second gaps, so that the first and second plungers are attracted toward the first and second fixed cores. |
