PURPOSE:To make a work easy and simple and to make a gap between cores extremely small by equipping the free end part of a back core on a front core and utilizing elastic substance to press-bond both cores by a slider. CONSTITUTION:In the slider 15 which positions on an upper side, a notch part 15k storing the flat spring 16 having a necessary shape is provided over the surface facing to the slider 4 and an internal surface in a horizontal direction. And the base part of the front core 11 is held between the sliders 4 and 15 and made to adhere so as to fix by forces of M and N directions shown by arrows. After that, the back core 12 holding coil bobbins 3a and 3b is pushed in until it abuts on the internal wall surface of the cutout part 15k against the elasticity of the flat spring 16 in order to respectively equip the head parts of the arms 12a-12d of the back core 12 on the corresponding slightly projecting free end parts of the front core 11 and press-contact the back core 12 to the front core 11 with the elasticity of the flat spring 16 so as to close magnetic circuits A and B.
