PROBLEM TO BE SOLVED: To provide a transplanter of trolley type capable of accurately planting seedlings even when the transplanter travels on a traveling surface with a lot of irregularities.SOLUTION: Crawler-type traveling devices 18 provided onto both left and right sides of a traveling machine body 9 are each supported by a transmission case 19 which is supported by the traveling machine body 9 at one end side, the traveling machine body 9 being supported by the transmission case 19 at the other end side. On the other end side of the transmission case 19, a drive shaft 41 for being rotated by transmission of a force from an engine 11 via a power transmission mechanism inside the transmission case 19, and a rocking support shaft 46 arranged below the drive shaft 41 are provided. The crawler-type traveling device 18 is constituted with a drive wheel 47 that rotates integrally with the drive shaft 41, front and rear idlers 48 and 49 located below the drive wheel 47, a track roller 50 between the front and rear idlers 48 and 49, a crawler belt 15 winded around the drive wheel 47, the front and rear idlers 48 and 49, and the track roller 50, and a rocking frame 51 rockably supported at an upper part thereof by the rocking support shaft 46 and for rotatably supporting at a lower part thereof the front and rear idlers 48 and 49 and the track roller 50.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、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の左右両側に設けたクローラ式走行装置18を、一端側が走行機体9に支持された伝動ケース19の他端側に支持し、伝動ケース19の他端側に、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回転駆動される駆動軸41と、この駆動軸41より下側に配置された揺動支軸46とを設け、クローラ式走行装置18を、駆動軸41と一体回転する駆動輪47と、駆動輪47より下側に位置する前後アイドラ48,49と、前後アイドラ48,49間の転輪50と、駆動輪47,前後アイドラ48,49及び転輪50にわたって巻き掛けられたクローラベルト15と、上部が揺動支軸46に揺動自在に支持され下部に前後アイドラ48,49と転輪50とが回転自在に支持された揺動フレーム51とから構成する。【選択図】図1
