SOLENOID OPERATING DEVICE AND OPENING AND CLOSING DEVICE USING SAME

摘要

An electromagnetically operated device (8) includes: a moving member (12) of the electromagnetically operated device (8); a drive coil (closing and opening coil) (10) that is energized to generate magnetic flux for driving the moving member (12); a permanent magnet (14) provided between a stationary member (11) and the moving member (12) for holding the moving member (12); and a holding force adjusting member (15) for adjusting the holding force applied to the moving member (12) by the permanent magnet (14), wherein the holding force adjusting member (15) is placed at a position that will not be included in the main magnetic path of the magnetic flux caused by the drive coil (closing and opening coil) (10) so as to be removable.
