<p>PROBLEM TO BE SOLVED: To provide carrying facility for realizing a branch and confluence unrestricted on a layout by forming straight line-shaped passage parts and a branch/confluent passage part by a rail device for staying little dust and dirt, and adding a simple structure to the rail device of a branch/confluent place. SOLUTION: Upward wheel support surfaces 11A and 12A and inward roller guide surfaces 11B and 12B are formed on a pair of rail bodies 11 and 12. A constant passage 10 comprises the straight line-shaped passage parts 51 and 52 and the branch/confluent passage part 53. The branch-confluent place is provided with straight line side guide bodies 15 and 16 running along the straight line-shaped passage parts and a branch/confluent side guide body 17 running along the branch/confluent passage part. A moving body 20 is provided with wheels 21 and side guide rollers 24 supported and guided by a wheel support surface and a roller guide surface. A direction regulating member 25 guided by sideways turning guide parts 15a, 15b, 16a, 16b, 18b and 19b of the guide bodies are constituted so as to be laterally freely movable between a position corresponding to the straight line side guide bodies and a position corresponding to the branch/confluent side guide body by a laterally moving means 30.</p> |
