<p>PURPOSE:To miniaturize the device by securing a space with a sufficient cross section area without receiving any restriction with respect to an inside space section by forming almost the same length of one end of the yoke of electromagnet device as that of the inside space section and providing the space for an armature enough for making an operation of contacting and separating at the side in position of an armature surface mounted on an edge section of the end for the inside space section. CONSTITUTION:An inside space section 2 is formed from an inside peripheral wall by winding up a coil 1 on a coil spool 3 having a rectangular inside space section 2 of electromagnet device. A york 4 is provided for a periphery of the coil 1 to form the york 4 constituted of one end 4a, the other end 4b and a coupling piece 4c in the shape of U, and one end 4a is placed in the inside space section 2. And, a flat supporting surface 4e is formed on the other end 4b, the end 4a is the same length as that of an axis direction in the inside space section 2, and a flat armature surface 4d located being sunk by one stage from the other end 4b of the end 4a is fixed in the inside space section 2 so as to form a space S for an armature 5 consisting of the magnetic materials to be capable of making an operation of contacting and separating at the side in the position of the armature surface 4d.</p> |
