Abstract

PURPOSE:To contrive reduction of the number of pats and assembly steps by arranging a pair of flexible pieces on both ends of a bobbin and holding a frame by the first click arranged on the opposite plane to said flexible pieces and arranging the second click for engagement to a mechanical board on any of the planes except the plane on which the first click is arranged. CONSTITUTION:For the assembly processes, after inserting a fixed iron core 15 into a center hole 13o of a bobbin 13 on which a coil 16 is wound, a frame 11 is inserted in the groove between ribs 13a, 13b and 13c, 13d. Then clicks 13e-13h of the bobbin 13 are forced to be extended by inclination of clicks 11c-11f and the frame is driven into untill the frame 11 reaches the stoppers 13p and 13q of the bobbin thereby engaging the clicks mutually. Movable iron core 14 is inserted in a hole 13o of the bobbin 13. For attaching it to the mechanical board 18, the ribs 13a-13d of the bobbin 13 are adjusted to openings 18c-18f and driven into them so that clicks 13i-13l of the bobbin 13 re narrowed toward the central direction by inclination of the front ends to be driven into them till stoppers 13m and 13n contact the mechanical board 18 thereby engaging the clicks 13i-13l in the mechanical board 18.
