PROBLEM TO BE SOLVED: To make it possible to grasp a traveling direction of a truck easily and accurately from a driver's seat. SOLUTION: A traveling dolly comprises a truck body 1 having a plurality of independent-shift-type wheel units R1, L1, of which steering angles are changed with steering wheels 4 on driver's seats 2A, 2B, respectively. The body 1 has a steering controller 3 comprising a master shaft steering angle calculating section 31 for calculating a target steering angle of a virtual master shaft set in the center among the wheel units in the front row in a traveling direction on the basis of a steering angle entered via one of the steering wheels 4, a turn center calculating section 32 for calculating a turn center position on the basis of a value calculated at the master shaft steering angle calculating section 31, and a wheel target steering angle calculating section 33 for calculating respective target steering angles of the wheel units R1, L1 on the basis of a value calculated at the turn center calculating section 32. A steering angle display 24 is also provided on respective touch panels 23A, 23B of the driver's seats 2A, 2B to display a shifted direction of the dolly body 1 on the basis of the target steering angle of the master shaft calculated by the master shaft steering angle calculating section 31.
