PROBLEM TO BE SOLVED: To provide an electromagnetic relay unit in which rust-proofing treatment at the joint part between an iron core and a yoke can be simply executed by pouring an insulating resin from the outside after assembling a relay unit. SOLUTION: The electromagnetic relay unit 10 is composed so that the iron core 1 assembled with a coil bobbin 4 wound around by a wiring 4a is insertingly fitted to a hole 2a formed to the yoke 2, an electromagnet block (A) is fixed to a base 3 which is constituted by joining the part where the iron core 1 is insertingly fitted to the hole part 2a by welding, and the base 3 is covered with a cover case 5. An insulating resin filling hole 3b penetrating inside the base 3 is formed to the part corresponding to a weldingly-joined part (B) between the iron core 1 and the yoke 2 on the bottom face of the base 3. The weldingly-joined part (B) is coated by filling the insulating resin through the insulating resin filling hole 3b. COPYRIGHT: (C)2007,JPO&INPIT
