<p>PROBLEM TO BE SOLVED: To prevent a corner part from being chipped when a conveying vehicle turns the corner part at a right angle and to prevent useless space from generating between the conveying vehicle after the turning and a wall surface forming the corner part. SOLUTION: When an overhead conveying vehicle V0 turns a corner part 2 of a second stocker S2, the overhead conveying vehicle V0 is curved at a right angle and is traveled and the overhead conveying vehicle V0 after the curved traveling is arranged at a position away from a second wall surface part 3 of the second stocker S2 by fixed space L by curving and traveling the overhead conveying vehicle V0 counterclockwise by the center angleα(α<90 deg.) on a first curved road K1 curved in the direction opposite to an original curving direction on this side of the corner part 2 and continuously curving and traveling the overhead conveying vehicle V0 clockwise by the center angle (α+90 deg.) on a second curved road K2 which is connected with the first curved road K1 and is curved in the same direction as the original curving direction.</p> |
