Abstract
A steering truck for steering a wheel axle of a truck has a solid lubricant application device at a position facing a flange of a wheel on the outer side of the wheel axle in the direction of travel in a truck frame. A solid lubricant is applied to freely make contact with and move away from the flange and a spring impels the solid lubricant towards the flange. A stopper restrains the solid lubricant from approaching the flange, By utilizing a forward and backward movement of the wheel axle in the travel direction caused by steering, the solid lubricant 3 makes contact only on the outer rail side toward which the wheel approaches when passing through a curved section. No contact occurs on the inner rail side from which the wheel moves away when passing through a curved section and when traveling through a straight section.
