Abstract
A directional control device for use in a movable toy such as a radio control car, which has a cylindrical magnet, a magnetic yoke disposed rotatably within the magnet and having an electromagnetic coil, and steering arms attached to driven wheels of the toy. The direction of the movable toy in motion can readily be changed selectively by applying a DC current of one polarity to the coil so as to electromagnetically rotate the yoke, thereby to turn the steering arms in conjuction with the rotating yoke.
