ABSTRACT:
When an electric motor is rotated normally, a left-hand driving wheel is rotated normally by a drive gear through a large gear, a left-hand small gear, and a left-hand driven gear, and a right-hand driving wheel is also rotated normally through a right-hand small gear, a swing gear, an intermediate gear, and a right-hand driven gear, thereby causing the vehicle toy to run straight. When the electric motor is switched to a reverse rotation, the left-hand driving wheel is rotated reversely, and the swing gear is brought into engagement directly with the right-hand driven gear to rotate the right-hand driving wheel normally. As a result, the vehicle toy makes a continuous turn at a small radius of rotation. Since the swing gear is turnably attached to a switch arm which is capable of turning about a gear shaft of the large gear, the swing gear is moved in accordance with the normal rotation and reverse rotation of the right-hand small gear, and brought into engagement with either of the intermediate gear and the right-hand driven gear.
