PURPOSE: To enable universal running to be attained in longitudinal and lateral directions of a crawler toy vehicle, which mounts only a motor, by forming in a stripe shape a conductor part, consisting of metal foil, on a plastic material through an insulating part of fixed width and alternately applying positive and negative voltages to the conductor part.

CONSTITUTION: A brush-provided-crawler toy vehicle 2 runs while receiving power from the upper of a running sheet 1, and it forms a conductor part 12 in a plastic substrate 11. The conductor part 12 is formed by considering stability or the like of the conductor part 12 in its resistance value with the method suitable by etching. The conductor part uses Al, Cu, Fe, etc., and the etching is desired to be performed with a material in use for a flexible printed circuit by using corrosion liquid of a ferric chloride solution or the like. It is necessary for a circuit to separate the conductor part 12, with positive voltage applied, from the conductor part 12, with negative voltage applied, through an insulating part. While power is fed from a terminal part. The power receiving brush- provided crawler toy vehicle 2 is only required to electrically connect a brush 21, motor 22 and driving wheels.
