PROBLEM TO BE SOLVED: To simplify a swiveling operation mechanism of a traveling vehicle and improve its swiveling operation performance; with the traveling vehicle including: a straight movement transmission 53 to transmit power of an engine 17 to right and left traveling sections 2, a swiveling transmission 54 to transmit the power to the right and left traveling sections through reverse rotation, a straight movement manual operation tool 13 for the straight movement transmission, and a swiveling manual operation tool 10 for the swiveling transmission. SOLUTION: A combine harvester includes a control body 131 rotatable about two perpendicularly intersecting axes P, S, wherein the control body controls the swiveling transmission to take swiveling action through a swiveling interlock mechanism 180 by forward/reverse rotation about the first axis P caused by the swiveling operation of the swiveling manual operation tool, and controls the straight movement transmission to take speed change action by forward/reverse rotation about the second axis S caused by the speed change operation of the straight movement manual operation tool, wherein the swiveling interlock mechanism includes an electric motor 193 for driving the swiveling transmission to take swiveling action.
