<P>PROBLEM TO BE SOLVED: To provide a relay device which reduces deterioration in contact reliability of a contact due to degassing accompanied with heat generation of a coil. <P>SOLUTION: The relay device 1 includes: a contact chamber 2 enclosing fixed contacts 12 and movable contacts 14; a movable part 15 which makes the movable contacts 14 contacted with and separated from the fixed contacts 12; and an electromagnet part 30 which drives the movable part 15. The movable part 15 includes a movable shaft 23 which is driven to the electromagnet part 30 and moved to an axial direction Ax. The electromagnet part 30 includes: a movable iron core 31 which drives the movable shaft 23 in the axial direction Ax; a coil 39 disposed on the outer peripheral side than the movable iron core 31; and a yoke 41 covering the outer periphery of the coil 39. The movable part 15 and the movable iron core 31 are disposed inside the contact chamber 2, and at least a part of the yoke 41 and the coil 39 are disposed outside the contact chamber 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
