PURPOSE: To smoothly change the direction of a comparatively large remote control toy by changing an exciting polarity to a rotor magnet by switching the direction of a current to be supplied to an electromagnetic coil, and surely turning the rotor magnet within the range of±90 deg.. CONSTITUTION: An electromagnetic coil assembly 24 is composed of an upper electromagnetic coil 32 and a lower electromagnetic coil 34, and a rotor magnet is housed in housing parts 40 and 42 so as to be rotated. A control member 20 is composed of a swing board 50 for which an engage hole 46 to be engaged with an eccentric shaft of a crunk 28 is bored on the side of upper terminal part and a bearing cylinder 48 is provided at a lower terminal part. On the upper terminal part side of this swing board 50, steering rods 18 and 18 are coupled on both sides, respectively with the engage hole 46 as a center. As a result, the swing board 50 is coincident with the turning direction of the rotor shaft 26 and swings to left or right with the supporting shaft 56 as a supporting point. Therefore, the steering rods 18 and 18 are displaced and wheels 12 and 12 can be turned to left or right.
