PROBLEM TO BE SOLVED: To provide a transplanter which can stably switch a uniform velocity passage and a non-uniform velocity passage without complicating a structure, in a transplanter which switches the uniform velocity passage for transmitting uniform velocity rotation power to a planting working machine side and the non-uniform velocity passage for transmitting non-uniform velocity rotation power to the planting working machine side.SOLUTION: A switching mechanism 48 switches a transmission passage to a uniform velocity passage side by a slide of a shit member 63 to one side of a switching shaft 47, and on the other hand, switches the transmission passage to a non-uniform velocity passage side by a slide of the shift member 63 to the other side of the switching shaft 47. The switching mechanism comprises a working mechanism 83 which slide-moves the shift member 63 to both directions of the switching shaft 47, and also comprises, at the working mechanism 83, an elastic member 94 which straddles a pivot when the shift member 63 is slid, and in which the energization direction to the shift member 63 is inverted.COPYRIGHT: (C)2014,JPO&INPIT【課題】植付作業機側に等速回転動力を伝動する等速経路と、植付作業機側に不等速回転動力を伝動する不等速経路との切換を行う移植機において、構造を複雑化させることなく、等速経路と不等速経路の切換を安定的に行うことが可能な移植機を提供することを課題とする。【解決手段】切換機構48は、上記切換軸47の一方側への前記シフト部材63のスライドによって等速経路側への伝動経路切換を行う一方で、切換軸47の他方側への前記シフト部材63のスライドによって不等速経路側への伝動経路切換を行う構造とし、シフト部材63を切換軸47の両方向にスライド移動させる作動機構83を備え、前記シフト部材63がスライドされた場合に支点越えして該シフト部材63への付勢方向が反転される弾性部材94を前記作動機構83に設ける。【選択図】図8
