PROBLEM TO BE SOLVED: To solve the problem such that in the rolling regulation mechanism of rolling-regulating means of a riding type rice transplanter, since a motor and a gear for changing the posture of a transplanting part are located at the central position in the right and left sides of a machine body, it is difficult to conduct the mounting or maintenance work of the rolling regulation mechanism.SOLUTION: This rolling regulation mechanism is provided by installing an electric motor (60) and a driving gear (61a) at a position deviated from the center in the right and left sides to one side in the right and left sides of the machine body, a speed reduction mechanism formed of the driving gear (61a) and a driven gear (61b) at a position deviated from the center in the right and left sides to the above one side in the right and left sides of the machine body, and a gearing position between the driving gear (61a) and the driven gear (61b) at a position deviated from the center in the right and left sides to the one side in the right and left sides of the machine body.COPYRIGHT: (C)2009,JPO&INPIT【課題】 乗用型田植機のローリング制御手段のローリング制御機構は、植付け部を姿勢変更するモータとギヤが機体の左右中心位置にあり、ローリング制御機構の組付けやメンテナンス作業が困難であった。【解決手段】 ローリング制御機構において、電動モータ(60)及び駆動歯車(61a)を機体の左右中心から左右一側方に偏った位置に設け、駆動歯車(61a)と従動歯車(61b)からなる減速機構を機体の左右中心から前記左右一側方に偏った位置に設け、駆動歯車(61a)と従動歯車(61b)との噛合位置を機体の左右中心から前記左右一側方に偏った位置に設けた。【選択図】 図5
