Abstract
A solenoid device includes at least one electromagnetic coil for generating a magnetic flux when energized, a fixed core constituting part of a magnetic circuit through which the magnetic flux passes, and plungers constituting the magnetic circuit together with the fixed core and configured to advance to and retract from the fixed core depending on whether the magnetic coil is energized or de-energized. The magnetic circuit is provided with a magnetic resistance part as a resistance for the magnetic flux. The plungers are configured to be attracted to the fixed core by energizing the electromagnetic coil.
