PROBLEM TO BE SOLVED: To enable the lateral and vertical motion of an auxiliary seedling feeder without impairing operability.SOLUTION: A transplanter has: a lateral turn support mechanism 25 and a vertical turn support mechanism 26 which support an auxiliary seedling feeder 7 so as to be laterally and vertically turnable on a support frame 24. The support frame 24 has: a pair of support column frames 27, 28 in a fore-and-aft direction and a connecting frame 29 which integrally connects the support column frames 27, 28 in the fore-and-aft direction. The lateral turn support mechanism 25 has: a first turn support shaft 32 which is oriented upwardly and a lateral turn support base 33 which supports the auxiliary seedling feeder 7 so as to be laterally turnable via the first turn support shaft 32. The vertical turn support mechanism 26 has: a second turn support shaft 40 which is arranged at an upper end of the rear side support frame 28 while being oriented laterally, and supports a rear end side of the lateral turn support base 33 so as to be vertically turnable and an adjustment mechanism 41 which is arranged at the front side support column frame 27, and supports a height of a front end side of the lateral turn support base 33 so as to be adjustable.COPYRIGHT: (C)2014,JPO&INPIT【課題】操作性を損なうことなく、予備苗供給装置の左右および上下回動操作を可能にする。【解決手段】支持フレーム24上で予備苗供給装置7を左右および上下回動自在に支持する左右回動支持機構25と上下回動支持機構26を備え、支持フレーム24は、前後一対の支柱フレーム27、28と、前後の支柱フレーム27、28を一体的に連結する連結フレーム29とを備え、左右回動支持機構25は、上下を向く第一回動支軸32と、第一回動支軸32を介して予備苗供給装置7を左右回動自在に支持する左右回動支持ベース33とを備え、上下回動支持機構26は、後側支柱フレーム28の上端部に左右を向いて設けられ、左右回動支持ベース33の後端側を上下回動自在に支持する第二回動支軸40と、前側支柱フレーム27に設けられ、左右回動支持ベース33の前端側を高さ調節可能に支持する高さ調節機構41とを備える。【選択図】図3
