Claims

[Scope of Claim for Utility Model Registration] (1) A contact spring driver holder that swings and holds the contact spring driver on the front flange of a coil assembly in which an iron core penetrates through the center and a yoke is provided on the outer periphery. The contact spring driver moves in a direction perpendicular to the axis of the coil, thereby displacing a contact spring disposed on one side or both sides of the coil assembly to turn on the contact. 1. An electromagnetic relay that is turned OFF and OFF, comprising means for preventing rotation of the contact spring driver that occurs when the contact spring driver is displaced in the operating direction. (2) As a rotation prevention means for the contact spring driver, a projection is provided on the lower part of the front flange part of the coil bobbin constituting the coil assembly so that the lower part of the contact spring driver can come into contact and slide. 2. The electromagnetic relay according to claim (1) of the utility model registration, further comprising a stopper having a shape. (3) As a means for preventing rotation of the contact spring driver, a flat plate-shaped pedestal is provided perpendicularly to the flange at the lower part of the front flange of the coil bobbin, and the upper surface of the pedestal prevents the displacement of the contact spring driver. A registered utility model further characterized in that a groove is formed in a direction parallel to the direction, and a projection corresponding to the groove and using both side surfaces of the groove as a guide is arranged substantially at the bottom of the contact spring driver. An electromagnetic relay according to claim (1). (4) As a rotation prevention means for the contact spring driver, the coil assembly is fixed on a base, and a groove is formed on the upper surface of the base in a direction parallel to the displacement direction of the contact spring driver; The utility model according to claim 1, further characterized in that a protrusion corresponding to the groove and using both side surfaces of the groove as a guide is disposed substantially at the bottom of the contact spring driver. Electromagnetic relay.
