Abstract
A motorized toy system having current collectors, movable up and down via an elastic member incorporated into a body of the motorized toy. The current collectors protrude on right and left sides of the body and slidably and uniformly contact pole plates disposed on upper end surfaces of side walls formed on both sides of a track. Permanent magnets are disposed at constant intervals on the track so as to alternate their polarities, and the permanent magnets are secured to a first yoke. Electromagnets are mounted in the body, and are secured to a second yoke.
