Claims

[Claims for Utility Model Registration] (1) A cross coil is formed by winding two coils around a coil bobbin in directions orthogonal to each other, and a magnetic rotor is formed inside the cross coil on the inner lower end surface of the coil bobbin. A braking ring is formed below the rotating shaft and positioned inside the silicon in the bearing recess, and each of the coils A cross-coil type indicator that drives the magnetic rotor to rotate by a predetermined angle in response to a composite magnetic field of magnetic fields generated by the coils when energized, wherein the cross-coil type indicator is characterized in that an uneven portion is formed on the outer peripheral surface of the brake ring. Coil type indicator. (2) Two coils are wound around a coil bobbin in directions orthogonal to each other to form a cross coil, a magnetic rotor is placed inside the cross coil, and a bearing recess for silicon filling is formed on the inner lower end surface of the coil bobbin. A braking ring is formed below the rotating shaft to be located inside the silicon in the bearing recess, and a coil is generated by energizing each of the coils. In a cross-coil type indicator that drives the magnet rotor to rotate at a predetermined angle in response to a composite magnetic field of magnetic fields, an annular recess is formed on the lower surface of the magnet rotor, and the bearing recess has an annular recess projecting upwardly from the periphery of the bearing recess. A cross-coil type indicator, characterized in that an annular protrusion that is received in an annular recess of a magnet rotor is integrally formed, and an uneven part is formed on the outer peripheral surface of the brake ring.
