PROBLEM TO BE SOLVED: To provide an effective arrangement of a transmission structure of a seedling- transplanting part, and a frame in a transplanter for transplanting seedlings in odd lines. SOLUTION: The transmission means 68 for transmitting the rotary power from a transplanting driving shaft 67 installed in the right and left direction so as to cross the transplanting driving shaft 61, to seedling-transplanting devices 53 at the right, center and left is arranged by deviating the transmission device 68 to the right or left side from the center in the right and left direction of a machine body, and a gear device 71 is arranged in the right and left side opposite to the central transmission means 68 in the transplanter for transplanting the seedlings in the odd lines, transmitting the rotary power of the transplanting driving shaft 67 to the seedling-transplanting devices 53 at each line through the transmission means 68, and transmitting the power to a lead cam shaft 72 for moving the seedling-carrying platform parallel to the transplanting driving shaft 61 in the right and left direction, through a gear device 71. Transplanting transmission cases 63R, 63C and 63L for housing the transmission means 68, and a gear case 61 for housing the gear device 71 are each independently installed, and each of the cases is connected by frame pipes 62R, 62C and 62L for housing the transplanting driving shaft 67 in the interiors to each other.
