The present invention relates to a track structure for a track car, which comprises: a pulley individually and rotationally mounted in the front and the rear at a side surface of a body of a track car, wherein a guide groove portion is provided in an outer circumferential surface; and a track member of which both ends are wound by the pulley, wherein a guide protrusion inserted into the guide groove portion protrudes in an internal side surface. A rib portion to reinforce rigidity protrudes in an external side surface of the track member to improve durability of a track. Moreover, a foreign substance attached to an external circumferential surface of the pulley is removed to reduce moving performance while being driven and prevent the track from being left, thereby significantly improving driving stability and stability. |
