PURPOSE:To facilitate switching between two parallel rails on which hangers travel, by providing a curved section in which a plurality of curved pieces connected with each other so that the rotating axis extends in the longitudinal direction are clamped between resilient plates, to constitute a switching means. CONSTITUTION:There are provided a plurality of curved pieces 1 each having a clamping section 1b at the center of a flange 1a and an insertion section 1c on the other end side of the clamping section 1b, and the clamping section 1b and the insertion section 1c of the adjacent curved pieces 1 are fitted together, and are rotatably coupled together by means of rotary shafts 2. There are provided two rows of curved pieces 1, and the outside of the flange 1a of each curved piece 1 are clamped by resilient plates 3, and is loosely fixed around the center thereof by means of a screw 4. Further, one end of the curved piece 1 is connected to a slide block 5, and the end thereof is connected to a stationary block 8. The stationary sections 8, 8' of the thus obtained two curved sections 11, 11' are connected with each other, and slide blocks 5, 5' are driven by drive devices 12, 12', and therefore, square rails 13, 14 or 15, 16 may be connected with each other.
