PROBLEM TO BE SOLVED: To provide a walking transplanter capable of transplanting seedlings on the field in good accuracy even when the transplanter travels on a traveling surface having many projections/recesses.SOLUTION: The transplanter is constituted as follows. A traveling machine body 9 includes crawler traveling devices 18 at right and left both sides, and the crawler traveling device 18 is supported by the other end side of a transmission case 19 one end side of which is supported by the traveling machine body 9. A driven shaft 87 rotatably driven around a right and left shaft by the power transmitted from an engine 11 through a power transmission mechanism in the transmission case 19 is provided in the other end side of the transmission case 19. The crawler traveling device 18 includes a driven wheel 99 integrally rotating with the driven shaft 87, front and rear idlers 100 and 101 positioned at in front and back of and below the driven wheel 99, an endless crawler belt 15 wound over the driven wheel 99 and the front and rear idlers 100 and 101, and a swinging frame 102 having an upper part supported by the transmission case so as to be swung around the axes X of the driven shaft 46, and the lower part having the front and rear idlers 100 and 101 supported so as to be freely rotatable around the right and left shaft.COPYRIGHT: (C)2010,JPO&INPIT【課題】 移植機が、凹凸の多い走行面を走行しても、圃場に苗を精度良く植え付けることができる歩行型の移植機を提供する。【解決手段】 走行機体9の左右両側にクローラ式走行装置18を備え、クローラ式走行装置18は一端側が走行機体9に支持された伝動ケース19の他端側に支持され、伝動ケース19の他端側に該伝動ケース19内の動力伝達機構を介してエンジン11からの動力が伝達されて左右軸回りに回転駆動される駆動軸87を設け、クローラ式走行装置18は、駆動軸87と一体回転する駆動輪99と、駆動輪99の下方側で且つ前後に位置する前後のアイドラ100,101と、駆動輪99及び前後アイドラ100,101にわたって巻き掛けられた無端帯状のクローラベルト15と、上部が伝動ケースに駆動軸46の軸芯X回りに揺動自在に支持され下部に前後アイドラ100,101が左右軸回りに回転自在に支持された揺動フレーム102とを備えてなる。【選択図】図1
