Abstract
A plurality of carriers are towed by a traction car moving along a guide portion provided under a travel road surface plate through flexible pulling members. Mobile models on the travel road surface plate are attracted to the towed carriers by magnets. Hence, the mobile models on the travel road surface plate travel in accordance with the movement of the traction car. Furthermore, when a plurality of winch units provided to the traction car are separately operated to take up and rewind the pulling members, the plurality of mobile models travel at different speeds.
