PROBLEM TO BE SOLVED: To provide a means for preventing conveyance members from breakages stemmed from bites of stone, sand or the like and from deterioration stemmed from sticking them with sand and stone, etc. in a chain-conveyor-type conveyance system for a vegetable harvester. SOLUTION: The means includes a pair of driving sprockets 35 and 35, a drive shaft 36 supporting the pair of driving sprockets, a pair of driven rollers 37 and 37, a driven shaft 38 supporting the pair of the driven rollers, and members (first conveying members 44, 44... and second conveying members 48, 48...) set across a pair of conveying chains 43 and 43 wound around the pair of driving sprockets and a pair of driven rollers and the pair of conveying chains and functioning to hold and convey harvested vegetables. In the means, the pair of driven rollers have an inner side 37c as a circular projection extended to the inner side in the direction of the driven shaft, while the outside outer circumference of the inner side lies close to the joining part between the conveying members going around the driven shaft and the conveying chains.
