<p>When a control device (6) starts to pass electricity in a first direction with respect to an electromagnetic coil (53), the magnetic force generated by a non-attractive magnetic circuit (MCb) becomes stronger than the attractive magnetic force generated by an attractive magnetic circuit (MCa), resulting in a movable member (55) being guided by a guiding section (57a) of a yoke (57) and moving from a first position to a second position. When the control device (6) starts to pass electricity in a second direction with respect to the electromagnetic coil (53), the attractive magnetic force generated by the attractive magnetic circuit (MCa) becomes stronger than the magnetic force generated by the non-attractive magnetic circuit (MCb), resulting in the movable member (55) being guided by the guiding section (57a) and moving from the second position to the first position. As a result, the ON-OFF movement process for the movable member (55) can be reliably performed.</p> |
