PROBLEM TO BE SOLVED: To prevent a spare seedling to be fed from dropping into a space between turning rollers in a spare seedling-feeding conveyor. SOLUTION: The spare seedling-feeding conveyor 7 for conveying the spare seedling Y from the front part to the rear part of a machine body is installed in a machine body side part of a riding-type rice transplanter. The spare seedling-feeding conveyor 7 is equipped with a plurality of the turning rollers 10 arranged at a prescribed interval in the spare seedling-conveying direction, and a feed guide 16 for preventing the spare seedling Y fed onto the starting terminal part of conveyance from dropping into the space between the turning rollers 10. The turning rollers 10 have right and left roller parts 10a and roller shaft parts 10b positioned between the right and left roller parts 10a, and formed so as to have diameters smaller than the roller parts 10a. The feed guide 16 is installed between the right and left roller parts 10a in the plane view, and in the lower part of the upper terminal of the roller part 10a and in the upper part of the upper terminal of the roller shaft part 10b in the side view.
