To provide a conveyer suitable for travelling and driving by a friction drive wheel arranged in a travelling path.

The conveyer 20 structured so that bar-shaped main bodies 21 of the conveyers 20 in front and on the back are linked each other or are abutted on each other at adjacent end parts, includes the bar-shaped main body 21 having a center bar shaped member 26 provided with a conveyed object support stand 22, and both end bar-shaped members 28A, 28B connected on both ends in front and on the back of the center bar-shaped member 26 so as to horizontally swing around vertical shaft cores 27a, 27b. Trollies 23, 24 are mounted on both ends in front and on the back of the center bar-shaped member 26 so as to horizontally swing around the vertical shaft cores 27a, 27b. The both end bar-shaped members 28A, 28B are linked with each of the trollies 23, 24 which share the horizontally swinging vertical shaft cores 27a, 27b, and horizontally swing integrally with the trollies 23, 24.
