Abstract:
1. An electromagnetic relay which moves a card by a movable iron fragment rotated in accordance with energization and de-energization of a coil wound around a barrel of an iron core to open and close a contact, one end of the movable iron fragment being rotatably supported on one of magnetic poles disposed at both ends of the barrel of the iron core, the other end of the movable iron fragment being opposed to the other of the magnetic poles such that the other end of the movable iron fragment can be attracted to the other of the magnetic poles, wherein: both arms as upstanding portions disposed at both ends of the barrel of a plate magnetic material which is punched to be substantially U-shaped as viewed from the front by press working are bended to form the magnetic poles having magnetic-pole surfaces extending in a horizontal direction; a vertical face passing through the center of the barrel crosses the centers of the magnetic-pole surfaces at right angles; and the width of the barrel is smaller than the height of the barrel.
