The present invention relates to a trailer having an extended loading space where a loading bed is separated and slides in a beam structure. In the trailer having the extended loading space which can extend the loading space by adjusting an interval between a front bed and a rear bed by separating a loading bed to load freight into the front bed and the rear bed and connecting the front bed and the rear bed by a slide beam, the trailer of the present invention can adjust the interval between the front bed and the rear bed easily by performing a slide operation smoothly by keeping the slide beam and a hole inserted with the slide beam in a horizontal state when extending or contracting the length of the loading bed, by comprising a horizontal adjusting apparatus which includes: a roller closely adhering to the ground by protruding from a lower part of the loading space; a fastening arm to change the height of the roller by being folded up and down, wherein the roller is mounted; and a cylinder for lifting up the roller or bringing the roller in contact with the ground by folding the fastening arm up and down. Moreover, the trailer comprises a simple structure of the roller, the fastening arm and the cylinder of the horizontal adjusting apparatus, and can be installed in a limited space without preparing an additional installation space by arranging the roller, the fastening arm and the cylinder in the frame constituting the loading space. |
