<P>PROBLEM TO BE SOLVED: To provide a three-dimensional legged roadway for the travel of a toy car with a motor, having a permanent magnet, in which part of the three-dimensional roadway is used in such a way that it is grounded with relation to a plane at three or more points to be prevented from falling. Ž<P>SOLUTION: The three-dimensional roadway 9 includes a strip-shaped plate of plastic material, with a metal rail 1 made of a magnetic material provided on its surface along a center. The whole body is formed in a circle with relation to a plane, and U-shaped legged roadway sections 3 are provided at three or more positions along the circle. Each legged roadway section 3 is formed in a loop by connecting one or a plurality of vertical roadway sections 7, twisted roadway sections 4, helical roadway sections 5, down-inclined roadway sections 6, flat roadway sections 2, and roadway sections 8 shaped otherwise.
