The present invention relates to a device to withdraw a tow dolly wheel assembly, which includes: a bracket having a sliding groove longitudinally formed in the upper part, and of which lower part is fixed to the floor of a boom of a towing vehicle; and a withdrawal member including a placement part, in which a tow dolly wheel assembly is reversely placed in the upper part, and a sliding part combined with the lower part of the placement part to slide in the sliding groove. According to the present invention, since the withdrawal member slides to the rear of the towing vehicle along the sliding groove of the bracket in order to make the tow dolly wheel assembly protrude, the tow dolly wheel assembly is able to be conveniently loaded to or unloaded from the towing vehicle. |
