PROBLEM TO BE SOLVED: To solve such the problems that a magnetic fault occurs when the conventional motorized toy car set with a permanent magnet is taken up from the metallic rail of a three-dimensional roadways after stopping a travelling play so as to be carried around, and then, is brought into contact with an IC card, a personal computer, or the like for a long period of time, and also a travelling fault occurs by rolling in the small-radius curves or the like of the three-dimensional roadways when the motorized toy car has fixed-shaft type four wheels.SOLUTION: The motorized toy car set is constituted by arranging a rectangular magnet base plate hole 9 in the chassis 3 of the motorized toy car 1, enabling a magnet base plate 8 to be fitted to the magnet plate hole 9, arranging the permanent magnet 5 on the front surface of the magnet base plate 8 and disposing rotary pieces 11 on both sides of the permanent magnet 5, fixing an operation shaft 14 to a magnet guard plate 12 and arranging a spring 13 on the rear surface, enabling one end of the operation shaft 14 to be put through the through-hole 16A of a support plate 16 and to be rotatable linked with a spring 13, arranging a switch pin 17 and a handle 18 at the other end, putting a magnetic guard box 20 on the upper part of the magnet base plate hole 9, and arranging a recessed guide groove 6A at the center and the metallic rail 7 on the bottom in the three-dimensional roadways. |
