Abstract
A toy vehicle travels on the surface of a travel board, following a path of magnetically attractive material. The toy vehicle has a single drive wheel located centrally on the bottom of the vehicle's body. The center of gravity of the vehicle resides substantially over the single drive wheel so that the vehicle is balanced. A magnet located in the front of the vehicle is attracted to the magnetic path on the travel board. The magnetic attraction directly steers the vehicle about the central drive wheel along the path.

A travelling toy guided by magnetic force capable of travelling along a guide path made of magnetically attractive material and provided on a travel board, said travelling toy comprising:
- a body having a bottom surface and a front end;
- means for driving said body forward along said guide path, said drive means being attached to said body and including a drive wheel which contacts said travel board, said drive wheel being located substantially in the center of said bottom surface so that the center of gravity of said toy resides substantially over said drive wheel;
- a magnet attached to said body in front of said drive wheel, said magnet being attracted to said magnetically attractive material of said guide path so that said magnet steers said body along said guide path as said toy is driven forward by said drive means, said magnet steers said body about said centrally located drive wheel;
- means for supporting said front end of said body above said guide board against the pull of said magnet and said magnetically attractive material.
