  • Patent number: 7710223
    Abstract: A relay includes a movable iron piece, a plate spring fixed to the one surface of the movable iron piece, a shaft hole formed by the one surface of the movable iron piece and the plate spring, and a supporting shaft inserted through the shaft hole. The movable iron piece is rotated round the supporting shaft based on excitation and nonexcitation of a magnetic unit. Both end portions of the plate spring alternately drive a contact point unit. The shaft hole is formed by a flat portion of the one surface of the movable iron piece and a bearing portion formed by subjecting the plate spring to bending work. The movable iron piece is supported so as to be rotatable.

  • Publication number: 20090219120
    Abstract: An electromagnet device has a movable iron piece having an end that is operable to contact and separate to and from a magnetic pole portion of an iron core. The movable iron piece rotates based on magnetization and demagnetization of a coil wound around the iron core. A tapered surface is formed on at least one end of an attraction surface of the movable iron piece, which attracts to and separates from the magnetic pole portion of the iron core. At least one contacting portion that is in flush with and continuous to the attraction surface and in contact with the magnetic pole portion of the iron core is arranged in a projecting manner on the tapered surface.
