PROBLEM TO BE SOLVED: To simply and easily open/close an area of crossing with a crossing passage of a travel path, when using the crossing passage of crossing with the travel path of a carrying travel body of traveling on a guide rail installed on a floor surface.SOLUTION: A travel path structure of the carrying travel body is constituted of a movable rail on which the area of crossing with the crossing passage 14 of the travel path of the carrying travel body, can horizontally move for opening-closing between a connection action position for connecting the mutual front-rear guide rails 9a and 9b of the crossing passage 14 and a lateral side retreat position of the crossing passage 14. The movable rail is constituted of the front-rear two movable rails 15 and 16 becoming serial when existing in the connection action position, and the respective movable rails 15 and 16 are rotatably journaled around vertical support shafts 19 and 21 in respective outer end parts positioned outside the crossing passage 14, and are provided with lock means 28 for connecting mutual inner end parts being mutually adjacent when both movable rails 15 and 16 exist in the connection action position. |
