TRANSPLANTER

To provide a transplanter capable of facilitating and surely performing work which changes a distance between wheels for performing planting in four rows by reciprocation, or the like.SOLUTION: A transplanter comprises: a machine body; a motor mounted on the machine body; a transplanting part provided on the machine body and planting seedlings in a farm field; drive wheels which support the machine body in a travelable manner, receives power from the motor to rotate; and power transmission shafts for transmitting the power of the motor to the drive wheels. The drive wheels comprise, one drive wheel provided on one side of a machine body width direction, and the other drive wheel provided on the other side of the machine body width direction. The power transmission shafts comprise one shaft to which, power from the motor is transmitted, and the other shaft for rotatably supporting the other drive wheel. The other shaft is coupled to the one shaft through a coupling part, so as to freely slide in the machine body width direction, and the coupling part has a first falling prevention part for preventing the other shaft from dropping off from the one shaft when sliding the other shaft.SELECTED DRAWING: Figure 53 【課題】往復４条植えを行うため等に車輪間の距離を変更する作業を容易に且つ確実に行うことができる移植機を提供すること。【解決手段】移植機は、機体と、前記機体に搭載された原動機と、前記機体に設けられて圃場に苗を植え付ける移植部と、前記機体を走行可能に支持し、前記原動機の動力を受けて回転する駆動輪と、前記原動機の動力を前記駆動輪に伝達する動力伝達軸と、を備え、前記駆動輪は、機体幅方向の一方側に配置された一方駆動輪と、機体幅方向の他方側に配置された他方駆動輪とを含み、前記動力伝達軸は、前記原動機からの動力が伝達される一方軸と、前記他方駆動輪を回転可能に支持する他方軸とを含み、前記他方軸は、連結部を介して前記一方軸に対して機体幅方向にスライド可能に連結され、前記連結部は、前記他方軸をスライドしたときに前記一方軸から離脱することを防ぐ第１抜け止め部を有している。【選択図】図５３
