A rack 111 is laid in the sloped region of the track 110. The conveying carriage 120 has wheels 122f and a pinion 124. The wheels 122f and the pinion 124 are driven through an axle 123f by a driving motor 125. The conveying carriage 120 travels with the wheels 122f in the horizontal region on the track 110, where the pinion 124 is apart from a bottom face 110a of the track 110.
