PROBLEM TO BE SOLVED: To provide a conveyance device capable of properly moving conveyance traveling bodies at a fixed interval by frictional driving.SOLUTION: In a specific frictional drive area A2, a frictional drive wheel 12 in pressure contact with a frictional face 10 formed on a load bar 3 of conveyance traveling bodies 1 is provided at an interval substantially equal to the total length of the load bar 3. In the specific frictional drive area A2, a frictional driving conveyance device capable of moving the conveyance traveling bodies 1 at a fixed interval is provided with an extension bar 14 which can be set in an extension posture extending in the extension direction of the load bar 3 or a storage posture not extending from the load bar 3, at the longitudinal end of the load bar 3. The tip of the extension bar 14 is provided with a contact part 14b in contact with the end of conveyance traveling bodies 1 which are located adjacent to each other when the extension bar 14 is in the extension posture, to prevent the adjacent travelling bodies 1 from relatively moving close to each other in the direction of reducing the fixed interval. |
