To provide a leveling valve easily attached to a vehicle body even when a large-size device such as an engine is arranged above a rigid axle.
This leveling valve 12 for a front wheel comprises a leveling valve body 12a, and a movable lever 13. The leveling valve body 12a is fixed to a cross member 9. The movable lever 13 is connected with one of a pair of rods parts 55, 55 of the V-shaped rod 10. The leveling valve 12 for the front wheel detects a displacement of a rigid axle 4 for a front wheel based on displacement of the movable lever 13 relative to the leveling valve body 12a. Accordingly, because the movable lever 13 need not be directly connected with the rigid axle 4 for the front wheel, the leveling valve body 12a can be arranged at a position separated from the rigid axle 3 for the front wheel, and the displacement of the rigid axle 4 for the front wheel can be surely detected at the separated position.
