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