PROBLEM TO BE SOLVED: To solve problems in achieving miniaturization and simplification of a conventional sulky rice transplanter wherein a front accelerator part and a rear accelerator part are integrally formed in an transmission case and central parts at right and left of a rear part of the transmission case protrude downward largely and abut on a center float, the center float is required to be retreated backward and thereby longitudinal length of a machine body is elongated in the well-known transmission case and that it is required to form the rear accelerator part in a portal shape in order to solve the problem but enlargement of an intermediate gear cannot be avoided at this time and a cost for producing parts is increased and weight of the machine body is also increased. SOLUTION: An intermediate shaft 31 for transmitting power from a side clutch shaft 35 to a rear wheel driving shat 69 is divided in two at the left and the right in a rear accelerator part 38. The left and the right intermediate shafts 23 and 24 are extended outer than the side clutch shaft 35.
