According to the present invention, safety of a worker on the truck, and work efficiency may be secured because each connection part of members constructing a truck main body (10) maintains a stable fixing state, and the position of the truck is quickly, accurately, and simply adjusted.

    본 발명은 차륜(21)이 구성된 캐스터(caster)(20)가 하부프레임(11)에 장착되어 레일을 따라 이동되는 철도 대차에 관한 것으로, 대차 하부 전, 후방 양측단부에 각각 캐스터(20)가 설치되되, 캐스터(20) 상부에는 암나사 형성 나선관(25)이 구성되고, 대차 저면에는 웜(33) 및 웜휠(32)이 장착되되, 웜휠(32)의 회전축으로서 수나사가 형성된 나선봉(31)이 연결되며, 전, 후방 캐스터(20)의 웜(33)이 동축(同軸)을 이루도록 배치되고, 각각의 웜(33)을 관통하는 결합공(35)이 형성되어, 전, 후방 웜(33)의 결합공(35)에 단일 결합봉(60)을 결합, 회전함으로써, 대차 전, 후방 캐스터(20)가 동반 승강될 수 있도록 한 것이다. 본 발명을 통하여, 대차 본체(10)를 구성하는 각 부재간 연결부위의 견고한 고정상태를 유지하면서도, 대차의 자세를 기민하고, 정밀하며, 간편하게 조정할 수 있어, 대차 탑승 작업자의 안전은 물론 작업 효율성을 확보할 수 있다.
