Abstract
A rotation control unit is disposed on an intersection portion. The rotation control unit has a plurality of blocks and extends into a running way of an automotive toy. As an automotive toy enters an intersection from a running way, the automotive toy pushes a block to rotate a rotation control unit. Due to this rotation, the block is moved away from the running way and the automotive toy on the running way is made movable. A block is placed on the other running way to close it so that the other automotive toy is prevented from entering the intersection portion. While the automotive toy is passing the intersection, the rotation control unit retains this state. After the automotive toy has passed the intersection portion, the pressure applied to the block is removed and the rotation control unit is returned to its original position, whereby the automotive toy can enter the intersection portion from the other running way.
