PURPOSE: To provide the inexpensive toy car race game which is insatiable regardlessly of the place of installation.

CONSTITUTION: A guard rail 3 is linked in the shape of a band by inserting its metal fittings to holes 11 of an opposite guard rail 3 to connect it and two large and small links are formed to form a desired driving course. In that case, a wavy guard rail 4 can be formed as well. Next, a median strip 5 is built up and fitted at any desired position on the driving course and a shock absorber 7 is fitted at an approach gate. Then, the width of the course is decided and supporters 6 are inserted and fitted to the fitting holes of the guard rail 3, wavy guard rail 4 and median strip 5 after its length is matched with the width of the course. Further, a direction changer 8 and a jump stand 9 are suitably mounted.
