Abstract: An inward surface of a flange 12 is formed with at least two coil guide grooves 14, 15 for start-up of coil winding, which grooves are in point symmetrical with respect to the central axis of a body 11 so that they are individually positioned between coil terminal holes 12a, 12b.

Abstract: An electromagnetic relay according to the present invention is applicable, for example, to a flasher relay to be mounted in automobiles, autobicycles or the like. When a driver of the automobile turns on the switch for the winker, the winker lamp is turned on and off and at the same time, a sound is generated to inform the driver of the fact that the winker lamp is being operated.

Abstract: The electromagnetic device comprises three parts of a coil spool, a yoke and a terminal block combined solidly, whereby the terminal block is held between a collar of the coil spool and the yoke, and both the ends of an iron core are fixed to the coil spool and the yoke.

Abstract: A hinge-type electromagnetic relay including a spool having a first flange and a second flange which is wound with a coil, a core inserted into the spool, an armature, a yoke, a movable contact and a stationary contact, comprising a molded plastic cover unit made of electrically insulating material which has at a bottom thereof an opening portion to enclose the spool, the second flange supporting coil terminals to be connected with the coil and being disposed to close the opening portion of the cover unit, and the cover unit supporting a stationary contact terminal carrying the stationary contact.
