PROBLEM TO BE SOLVED: To provide a transplanter capable of preventing the transmission of reverse rotating power to a vertical sending mechanism efficiently and also at a low cost without separately installing a special member such as a one-way clutch or the like other than a transplanting clutch intermittently transmitting power to a transplanting implement side, and constituted by a seedling-loading stand, the vertical sending mechanism, transplanting claws, or the like.SOLUTION: The transplanter includes a transplanting clutch 66 for intermittently transmitting the power to the transplanting implement side in the middle of a power transmitting route from a branching mechanism to the transplanting implement, installing regulating means 78 for stopping the transplanting claws at a predetermined attitude by limiting the cutting motion of the transplanting clutch 66 when a rotary body 73 constituting the transplanting clutch 66 is positioned at other than a cutting range L which is a predetermined phase range, and setting the cutting range L so as to prevent that a vertical sending arm makes a contact with a vertical sending lever from above by transmitting the reverse rotating power to the branching mechanism to swing the vertical sending lever downward.COPYRIGHT: (C)2011,JPO&INPIT【課題】苗載せ台や縦送り機構や植付爪等によって構成される植付作業機側への動力伝動を断続させる植付クラッチ以外に、ワンウェイクラッチ等の特別な部材を別途設けることなく、縦送り機構への逆転動力の伝動を効率的に且つ低コストで防止できる移植機を提供する。【解決手段】分岐機構と植付作業機との動力伝動経路の途中に、植付作業機側への動力を断続する植付クラッチ66を備え、該植付クラッチ66を構成する回転体73が所定位相範囲である切断範囲L以外に位置する場合には該植付クラッチ66の切断作動を規制することにより植付爪を所定姿勢で停止させる規制手段78を設け、分岐機構に逆転動力が伝動されることにより縦送りアームが縦送りレバーに上側から当接して該縦送りレバーを下方揺動させることを防止すべく該切断範囲Lを設定する。【選択図】図7
