PROBLEM TO BE SOLVED: To stably support both ends of a transversely feeding screw with a supporting frame having a sufficient strength. SOLUTION: This transmission structure for a planting part in a riding rice transplanter is composed by fixing a planting driving case 22 for supporting one end of a transversely feeding screw 46 and rotating and driving the transversely feeding screw 46 to a connecting pipe 71, fixing a supporting member for freely rotatably supporting the other end of the transversely feeding screw 46 to the connecting pipe 71, arranging the transversely feeding screw 46 so as to deviate the left and right center of the transversely feeding screw 46 to either one of left and right sides relatively to the left and right center of the connecting pipe 71 and rotating and driving the transversely feeding screw 46 to thereby reciprocate, transversely feed and drive a seedling-carrying platform in the left and right directions. |
