PROBLEM TO BE SOLVED: To provide a transplanter of trolley type capable of accurately planting seedlings in an agricultural field even when the transplanter travels on a traveling surface with a lot of irregularities.SOLUTION: On both left and right sides of a traveling machine body, provided are front wheels each provided to a front wheel support arm which is supported by a traveling machine body at one end side, the front wheel being provided to the other end side of the front wheel support arm, and crawler-type traveling devices each supported by a transmission case which is supported by the traveling machine body at one end side, the traveling machine body being supported by the transmission case at the other end side. On the other end side of the transmission case, a drive shaft and a rocking support shaft arranged below the drive shaft are provided. The crawler-type traveling device is constituted with a drive wheel that rotates integrally with the drive shaft, front and rear idlers located below the drive wheel, a track roller located between the front and rear idlers, a crawler belt winded around the drive wheel, the front and rear idlers, and the track roller, a rocking frame supported at an upper part thereof by th rocking support shaft 46 so as to be rockable about the shaft center and for supporting at a lower part thereof the front and rear idlers and the track roller, and a restrictor for restricting rocking of the rocking frame around the pivot support shaft by engaging with an engage part provided to the transmission case.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】 走行機体の左右両側に、一端側が走行機体に支持された前輪支持アームの他端側に設けた前輪と、一端側が走行機体に支持された伝動ケースの他端側に設けたクローラ式走行装置とを備え、伝動ケースの他端側に、駆動軸と、駆動軸より下側に配置された揺動支軸とを設け、クローラ式走行装置は、駆動軸と一体回転する駆動輪と、駆動輪の下側に位置する前後のアイドラと、前後アイドラ間に位置する転輪と、駆動輪,前後アイドラ及び転輪にわたって巻き掛けられたクローラベルトと、上部が揺動支軸46に軸芯回りに揺動自在に支持され下部に前後アイドラと転輪とが支持された揺動フレームと、伝動ケースに設けた係合部に係合することで揺動フレームの揺動支軸回りの揺動を規制する牽制具とを備えてなる。【選択図】図1
