필요 충분한 윤활 작용을 유지하면서, 윤활재의 마모를 억제한다. 대차의 윤축(2)을 조타 가능하게 구성한 조타 대차(11)이다. 대차 프레임(1)에 있어서의 윤축(2)의 차량 진행 방향 외측 부분의 차륜(2a)의 플랜지(2aa)부와 상대하는 위치에, 플랜지(2aa)부에 대한 접리 이동이 가능하도록 부착한 고형 윤활재(3)와, 고형 윤활재(3)를 플랜지(2aa)부측에 탄성가압하는 스프링(4)와 곡선 구간 통과시에, 조타에 의한 윤축(2)의 차량 진행 방향의 전후 동작에 의해서, 차륜(2a)이 가까워지는 외궤측만 접촉하고, 곡선 구간 통과시에 차륜(2a)이 멀어지는 내궤측 및 직선 구간 주행시는 접촉하지 않도록, 고형 윤활재(3)의 플랜지(2aa)부에 대한 접근 이동을 구속하는 스토퍼(12)를 갖는 고형 윤활재 도포 장치를 배치한다.

    [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.
