PROBLEM TO BE SOLVED: To erect dominoes pieces in parallel along the running track of a rear wheel even at the time of a turning by providing front wheel having a steering function, a means which performs a piece erecting between rear wheels on a car body equipped with the rear wheels as driving wheels, and a means which lets the rear wheel on the outer wheel side only come into contact with the ground at the time of a turning. SOLUTION: A car body 1 is made to run by applying a driving force to right and left rear wheels 2a by transmitting the rotation of a driving motor 7 to right and left small gears 13a through a worm gear train or the like. In the car body 1, a piece feeding mechanism 16 including a claw member 17 which feeds out a group of pieces D in a tower body 5 from the lowest one while adjusting to a running timing is provided. Then, the fed out piece D is made to reach a piece erecting location between the rear wheels 2a, 2b through a slider, and the pieces are arranged and erected in order. Also, at the time of a turning for which a front wheel 3a is steered, the car body 1 is tilted by a floor face pressure which a front wheel on the inner wheel side receives, and in the meantime, the rear wheel on the inner wheel side is lifted from the floor face. By this method, a pitch for the pieces which are erected in parallel is kept at a correct dimension.
