PURPOSE:To make a simple structural and low-cost device though stroke is short by supporting one end of opposing paired iron pieces by a shaft with free movement wherein a coil is wound on the central part at one of the iron pieces and the iron pieces absorb each other at other ends of the iron pieces in structure. CONSTITUTION:A coil 5 is wound on around the center of an iron piece 4 and a supporting section 6 bent opposite end sections of the width direction is formed at one end section of the iron piece 4 and a suction section 7 having a relatively wide area bent in reverse L shape is formed at the other end section. A flat plate-shaped iron piece 8 is arranged by opposing to such the iron piece 4. A supporting section 9 is formed by bending the opposite ends of the width direction at one end section of the iron piece 8. The iron pieces 4, 8 are connected with free movement by inserting and penetrating a shaft 10 under the condition that the supporting sections 6, 9 are overlapped. With the coil 5 excited, the suction section 7 and the tip end section of the iron piece 8 are absorbed. |
