<p>PURPOSE:To improve durability, by placing an oscillation coil and an iron core on the body side, positioning an iron core having teeth in a magnetic closed circuit of the first mentioned iron core to be coated with a rotation command shaft and a power shaft, and varying the magnetic reluctance in accordance with movement of the second mentioned iron core. CONSTITUTION:A coupling 9 is fixed to the power shaft 6 that is driven by a motor, and is resiliently connected through a resilient rubber 10 to the rotation command shaft 2 connected to a steering wheel. The shaft 2 is provided with a pin 11 so that when the shaft 2 is rotated a prescribed range, the pin 11 engages with a hole 12 in the coupling 9. The closed circuit iron core 13 having teeth 22 is fixed to the rotation command shaft 2, a resin 15 to which the magnetic reluctance varying iron core 14 having teeth 22 is integrally formed is fixed to the coupling 9, and the magnetizing iron cores 17, 18 are fixed on the body side. The iron cores 17, 18 support a coil 20 to which a lead wire 21 is connected.</p> |
