PROBLEM TO BE SOLVED: To provide a transportation truck appropriate for safely transporting a heavy load by securing excellent operability and stable running. SOLUTION: A pair of front roller units 12 are rotatably borne on a front lower surface of a deck 11, and a rear roller unit 13 is rotatably borne on a rear lower surface of the deck. A draw bar 14 is forward protruded from a front part of the deck and supported free of oscillating in the transverse direction. When the draw bar 14 oscillates in the transverse direction, both the front roller units 12 are rotated operatively associated with the oscillation in the same direction by a first link mechanism. When the front roller unit 12 rotates, the rear roller unit 13 is rotated in the reverse direction by a second link mechanism. The respective roller units 12, 13 have rotatably supported rollers 16 respectively. COPYRIGHT: (C)2003,JPO
