摘要： PURPOSE: An electromagnet fixing structure of an electromagnetic relay and a method of fixing the electromagnet are provided to increase an attraction force of an electromagnet exerting on the armature without an increase of cost, and to manage the thick dimensions when the yokes are manufactured. CONSTITUTION: An electromagnet fixing structure for the electromagnetic relay fixes a yoke(11) and an iron core(12), which form an electromagnet. In the fixing structure, a yoke(11), shaped like L, includes a bent surface portion(111). A rectangular through hole(112) is formed in the central portion of the bent surface portion(111). A rod-like iron core(12) is formed which has a cross section larger in the longitudinal direction than the rectangular through hole(112). A protruded portion(121) of which the end face(121a) is somewhat smaller than the through hole(112) is formed at the central portion of one end of the iron core(12). The yoke(11) and the iron core(12) are fixed by inserting the protruded portion(121) into the through hole(112). Circular holes(113,114) are formed in the yoke(11). A flange(122) is formed at the other end of the iron core(12), while being separated from and facing the bent surface portion(111). A length(L121) of the protruded portion(121) is selected to be longer than a length(L112) of the through hole(112). The yoke(11) and the iron core(82) in the electromagnet fixing structure are used together with a coil block(13) which includes a cylindrical bobbin(131) on which a coil(132) is wound and a pair of coil terminals(133) electrically connected to the coil(132), whereby an electromagnet is formed. Here, the yoke(11) and the iron core(12) are both fixed temporarily.
