A structure with idle rollers is intended for guide walls of goods conveyors comprising a surface for conveying the goods and at least one plate-like wall element extending longitudinally along the conveyor surface, adjacent to at least one of its edges, following its path. Roller-carriers each having a predetermined number of rollers mounted idly on axles and rotatable about rotation axes are snap-fitted on the plate-like wall element. The ends of the axles are supported by plates carried by the roller-carrier. The length of each roller-carrier depends on the minimum radius of curvature encountered in the path of the goods-conveying surface of the conveyor. The roller-carriers are connected to one another by snap-engagement members. The ends of the axles of the rollers are also snap-fitted in respective seats in the plates of the roller-carrier.
