PROBLEM TO BE SOLVED: To provide a passenger management machine which is advantageous in terms of cost and maintainability by standardizing the shape of parts. SOLUTION: The wheels are located between a pair of left and right wheels 2 and 3 and a pair of left and right wheels 2 and 3 in a plan view, and are located above a pair of left and right wheels 2 and 3, and are rotationally driven based on the power of a prime mover. It is possible to extend downward from the left and right central transmission shafts 42F and 42B and the left and right central transmission shafts 42F and 42B, and to transmit the rotational drive of the central transmission shafts 42F and 42B to the left and right wheels 2 and 3, respectively. A pair of left and right vertical transmission shafts 45, a horizontal central transmission case 41F, 41B accommodating the central transmission shafts 42F, 42B, and a vertical transmission shaft 45 extending downward from each of the left and right central transmission cases 41F, 41B. It has a pair of left and right kingpin cases 44 and 46 to be accommodated, each of the vertical transmission shafts 45 has the same shape, and each of the kingpin cases 44 and 46 has the same shape.
