To provide a toe-in adjusting mechanism of an industrial vehicle embodied in a simple configuration and capable of adjusting the direction and amount of the toe-in of the steered wheels.

The steered wheels 13L and 13R on the left and right are tied together through a cylinder rod 5 of a power steering device, and to the ends of the cylinder rod 5 a left 10L and a right coupling member 10R are coupled. A motor 24 rotates the cylinder rod 5 round its axis, and screw mechanisms 11L and 11R to move the coupling members 10L and 10R with respect to the cylinder rod in association with the cylinder rod 5 are provided in the coupling part of the cylinder rod 5 with the coupling members 10L and 10R. The screw mechanism 11L is formed as left-handed threads while the other 11R is formed as right-handed threads, and the thread pitches of the screw mechanisms 11L and 11R are formed equally to one another.
