PROBLEM TO BE SOLVED: To provide a solenoid device which can individually attract a plurality of plungers onto a stationary core and, when concurrently attracting the plurality of plungers, can reduce power consumption of an electromagnetic coil.SOLUTION: When each of a first electromagnetic coil 2a and a second electromagnetic coil 2b is energized, a part of magnetic fluxes Φ of the second electromagnetic coil 2b run through a first plunger 3a. At that time, when energizing the first electromagnetic coil 2a is stopped with the second electromagnetic coil 2b kept energized, the first plunger 3a is kept at an attraction position while a second plunger 3b is being attracted onto a second stationary core 5b by magnetic fluxes Φ of the second electromagnetic coil 2b. |
