PROBLEM TO BE SOLVED: To provide a branching device which can dispense with the installation of a flange in a wheel thereby improving the durability of the wheel and decreasing the energy consumption thereof and can reduce a load to be applied on a guide roller when displacement caused by a sharply bent corner is occurs. SOLUTION: A pair of guide rollers 231 are arranged in a truck unit 20d separately from the wheel 221 and a horizontal load can be supported by the pair of guide rollers 231. As a result, it is unnecessary to install the flange in the wheel 221 and the durability of the wheel 221 can be improved and the energy consumption can be decreased. Since a guide body 232 to/from which the pair of guide rollers 231 are attached and detached is connected rotatably to a deck 210 by a supporting shaft 233, the guide body 232 can be rotated relatively to the deck 210 via the supporting shaft 233 and the load applied on the pair of guide rollers 231 can be reduced as a result even if the displacement caused by a sharply bent corner occurs between movable beams upon changing a track.
