PROBLEM TO BE SOLVED: To properly stabilize the transplanted posture of a seedling regardless of a set interval of roots by operating a seedling-transplanting device in an irregular speed at a proper irregular speed transmission ratio so as to correspond to the set interval between the transplanting roots in a seedling transplanter having a seedling-transplanting part carrying the seedling-transplanting device for transplanting the seedlings on a field and installed in a traveling car body, constituted so that the power from a motor may be transmitted through a transmission route for the transplantation to the seedling-transplanting part at a speed proportional to the traveling speed of the traveling car body, and having an irregular speed-transmission mechanism for operating the seedling-transplanting device at the irregular speed so as to match with the cycle for transplanting the seedlings, installed in the transmission route for the transplantation. SOLUTION: This seedling transplanter has two or more irregular speed transmission gear pairs 33c, 33d, and a slide key 34 for switching the transmission state between the first transmission state in which the power is transmitted at the irregular speed through the two or more irregular speed transmission gear pairs 33c, 33d to the seedling-transplanting part, and the second transmission state in which the power is transmitted at the irregular speed through only the irregular speed transmission gear pair 33c as a part of the two or more irregular speed transmission gear pairs 33c, 33d to the seedling-transplanting part.
