|Title:||SELF-HOLDING SOLENOID AND TOOTH CLUTCH|
In order to provide a configuration that enables a large thrust force and a large movement stroke to be obtained with a slider, and that has an energy-saving characteristic, the present invention is equipped with an energization control unit which, when the slider is moved from a first position to a second position, energizes a first coil so as to produce a magnetic field that cancels out the magnetic flux of a permanent magnet around the first coil while a second coil is in the energized state.
