A traveling control device of a vehicle, wherein a steering cylinder (17) is controllably operated so that the steering angle of front wheels (11a) (steering wheels) detected by a steering angle detector (62) becomes the target steering angle of the front wheels (11a) set according to the operating state of a steering knob (42). The target steering angle of the front wheels (11a) (steering wheels) set according to the operating state of the steering knob (42) is compared with the detected steering angle of the front wheels (11a) detected by the steering angle detector (62). When a difference between the target steering angle and the detected steering angle is equal to or larger than a prescribed value, the traveling speed of the vehicle (10) is restricted so that the traveling speed of the vehicle (10) is less than the prescribed speed.
