Description of the Related Art In a conventional rotary solenoid, two permanent magnets are adhered and fixed at 180 degrees to a shaft, and a fixed iron core is provided with two convex portions facing toward the center, and a coil wire is provided there. It is configured to be wound directly via a bobbin. Then, by applying a voltage to the coil wire, the magnetic field generated in the convex portion of the fixed iron core and the magnet on the shaft side are attracted or repelled, and a rotating operation is obtained.
