PROBLEM TO BE SOLVED: To provide a travelling toy with magnetic wheels without specially providing a driving mechanism. SOLUTION: The travelling toy with magnetic wheels 1 has the same polarity as that in the inner space of wheels 2 made of a permanent magnet and the opposite polarity is adopted on the upper surfaces of the guide permanent magnet 5 of a slope 6 and the reinforcing permanent magnet 9 of a rocking board 10. The front end of the rocking board 10 is closed to the slope 6 and, in the meantime, the rear end is gradually separating in position relation. The rear end has a grip 12 and a projection 13. Though the wheels 2 placed on a horizontal board 7 are attracted in the direction of the slope 6, a magnetic force on the slope 6 is weakened at a lower part and gradually increased toward the front end so that the wheels 2 are moved upward on the slope 6. When the wheels 2 are stopped at the front end and the rocking board 10 is moved upward by operating the grip 12, the magnetic force is change on the slope 6 so that the stopped wheels 2 begin moving downward.
