<p>[OBJECT] To maintain a necessary and sufficient lubricating action while at the same time reducing wear on the lubricant. [MEANS] A steering truck 11 is designed to be able to steer a wheel axle 2 of a truck. A solid lubricant application device is disposed at a position facing a flange 2aa of a wheel 2a on the outer side of the wheel axle 2 in the direction of travel in a truck frame, and has a solid lubricant 3 applied so as to freely make contact with and move away from the flange 2aa, a spring 4 which impels the solid lubricant 3 towards the flange 2aa, and a stopper 12 for restraining the solid lubricant 3 from approaching the flange 2aa, so that by utilizing a forward and backward movement of the wheel axle 2 in the travel direction caused by steering, the solid lubricant 3 makes contact only on the outer rail side toward which the wheel 2a approaches when passing through a curved section, whereas not making contact on the inner rail side from which the wheel 2a moves away when passing through a curved section and when traveling through a straight section.</p> |
