To provide such a rail for an electric toy car with a pair of driving wheels whose direction can be changed that will prevent the toy car from hitting against a wall so often and will not require a support from a parent, etc., to smoothly drive the toy car even when a small child is on the toy car and the child cannot operate the steering of the toy car well enough.

This rail 1 is used with a toy car 5. On the driving surface 15 on the rail 1, a guiding protrusion 16 extending in the direction of the extension of the rail 1 is formed to be placed between a pair of driving wheels of the toy car 5. The toy car 5 can be driven along the rail 1 as the driving wheels are guided by the guiding protrusion 16. The rail 1 consists of a combination of straight rail units 2 and curved rail units 3 which are connected to each other, and a course layout can be variously changed.
