To provide a racing game device where a plurality of traveling bodies are simultaneously operated with high accuracy.

A racing game device comprises a host 7 for dividing one race into control periods and transmitting the traveling control data for specifying the moving amount of every control period, of the trucks 4 which form a plurality of traveling bodies to the corresponding truck 4, each truck 4 respectively stores the received traveling control data in a memory 87, so that it is traveled on the basis of the data by successively reading the traveling control data while counting the control period by an internal timer 84, and further the control period of the truck 4 is changed on the basis of the period changing command to change the speed. Whereby the speeds of all the trucks can be changed with the same ratio to be agreed with the speed of the abnormal truck 4 by changing the control period, even when the truck 4 which can not be traveled at the target speed is generated, the race scenario can be kept as it is, and a plurality of traveling bodies can be simultaneously operated with high accuracy.
