PURPOSE:To enhance the smooth operation by forming a plurality of ceiling rails, a turn table, a table driving mechanism, a running body having wheels having shaft centers in respective different positions to the advancing direction, and a moving wall running mechanism. CONSTITUTION:The rotating force of a running motor 84 is transmitted to a rotating sleeve 83, which rotates a sprocket 82 engaged with a chain 81 fixed to a ceiling rail 11 to self-advance a running body 6 within the rail 11. At the time of passing an intersecting point A, two running bodies 6 are guided to a movable rail 22, and a turn table 2 is turned by a table driving mechanism 3 to conform the running bodies with the end part of ceiling rails 12, 13. Then, the wheels 62 of the running body 6 are successively passed through a rail joint X1 from the wheel 62 on the front end side toward the advancing direction, and the running body is run over the joint X1 without any wheel 62 being dropped into the joint. Hence, smooth operation can be conducted. |
