PROBLEM TO BE SOLVED: To provide a wheel steering device of a traveling body capable of preventing occurrence of any partial wear in a rail traveling mode. SOLUTION: In the wheel steering device of the traveling body traveling on right and left rails via right and left front and rear wheels, front and back T-shaped levers 7, 8 are turned by right front and back wheels 2FR, 2BR to be turned by the turning anglesθ1,θ2 following the rail RR through guide wheels 3R, 3L via input parallel links 5, 6, and front and back output levers 11, 12 are turned by vehicle width output units 7b, 8b of the T-shaped levers 7, 8 via vehicle length displacement transmission units 13, 14 to turn left front and back wheels 2FL, 2BL by the turning anglesθ3,θ4. In this condition, correction-supporting pins 11b, 12b of the output levers 11, 12 are moved in the vehicle width direction by the correction displacement of one half of the difference in the front and back displacements in the vehicle width direction taken out the vehicle width output units 7b, 8b of the T-shaped levers 7, 8 by an inner-outer wheel difference correction unit 15, and the turning anglesθ3,θ4 of the left front and back wheels 2FL, 2BL are corrected thereby.
