PROBLEM TO BE SOLVED: To provide a transportation mechanism of a concrete product which guides a transportation dolly along a curve without forming a guide groove in the concrete and achieve reduction of costs and simplification of work process.SOLUTION: One rail 14 is detachably attached to a travel path 12 of a transportation dolly of a concrete product. The transportation dolly includes a direction control part 19 which is guided by the rail 14. The direction control part 19 includes a wheel 25 disposed on the rail 14. A contact surface width P of the wheel 25 relative to the rail 14 is formed larger than a width of the rail 14. Further, flange parts 28 are formed at both end parts of the wheel 25. |
