In the problem to be solved, in a ceiling side of an article transport facility, a ceiling transport vehicle performing article transport can be driven at various curvature curves for a layout degree of freedom of a driving rail to be increased. According to a solution, driving wheels (42I, 42E) enabling a ceiling transport vehicle (20) to be driven along driving rails (30I, 30E) and driven wheels (44I, 44E) independently rotated with the driving wheels (42I, 42E) are individually installed in a left and a right side with respect to a transport direction of the ceiling transport vehicle (20). In a straight section, the driving wheels (42I, 42E) in a left and a right side can be supported by each driving rail (30I, 30E). In a curved section, a driven wheel (42I) in an inner circumferential surface can be supported by a driving rail (30I), and moreover, the driving wheel (42E) of an outer circumferential side can be supported by the driving rail (30E) of an outer circumferential side.

    (과제) 물품 반송 설비의 천정측에서 물품의 반송을 행하는 천정 반송차가 여러 가지 곡률의 커브를 주행할 수 있도록 해서 주행 레일의 레이아웃 자유도를 높인다. (해결 수단) 천정 반송차(20)를 주행 레일(30I, 30E)을 따라 주행시키는 구동륜(42I, 42E)과, 구동륜(42I, 42E)과는 독립적으로 회전하는 종동륜(44I, 44E)을 천정 반송차(20)의 반송 방향에 대한 좌우 양측에 각각 설치하고, 직진 구간에 있어서는 좌우 양측의 구동륜(42I, 42E)이 각각 주행 레일(30I, 30E)에 지지되도록 하고, 커브 구간에 있어서는 내주측의 종동륜(42I)이 내주측의 주행 레일(30I)에 지지되며 또한 외주측의 구동륜(42E)이 외주측의 주행 레일(30E)에 지지되도록 구성한다.
