Abstract
An apparatus for controlling tension of a track, and more particularly to an apparatus for preventing a track wheel from separating due to an uneven road surface and obstacles on the road surface by minimizing space between a moving idler and roller when controlling the tension of the track, and for supporting the weight of a machine more safely by maximizing the space between a rear roller and a front roller. To this end, the present invention is characterized by: a track frame structure in which the idler and the front roller move together when controlling the tension of the track; and a damping member for absorbing external shock, wherein the idler is fixed in an idler frame, the front roller is fixed in a roller frame, and the buffer member is positioned between the idler frame and the roller frame.
