Abstract: A direction changing device for moving toys to be operated by a wireless remote-control system, wherein an operating rod is laterally slidably disposed in parallel with a wheel shaft so as to be engaged with any one of a plurality of recessed portions formed in a disc concentrically fitted inside any one of the wheels at both ends of the wheel shaft, when the rod is caused to move in that direction by an energized electromagnet which attracts a movable iron piece connected with the operating rod. The wheel, the rotation of which is stopped by the engagement of the operating rod with the engaging disc, becomes a pivot for turning the body of the moving toy in any desired direction.
