<p>This invention is provided with an electromagnet block (2), wherein a coil (24) is wound around an iron core (22) with a spool (23) interposed therebetween, and a yoke (41) that has one end thereof anchored to one end section of the iron core (22) is made to extend to a section at the side of a magnet pole section (25) at the other end of the iron core (22). A hinge spring (44) is anchored to the yoke (41), and a moving iron (4) is provided pivotably in a state of being supported by the hinge spring (44), with the other end of the yoke (41) functioning as a fulcrum. The hinge spring (44) is provided with an elastic contacting section (46) that extends from the position where the hinge spring (44) is anchored to the yoke (41), towards a direction opposite the position where the moving iron (4) is supported. The moving iron (4) has integrated therewith, at a side opposite a section (63) to be drawn with respect to the fulcrum, a card member (65) that can come in contact with the elastic contacting section (46) before coming in contact with the yoke (41).</p> |
