PROBLEM TO BE SOLVED: To provide a riding type rice transplanter which smoothly moves mat-like seedlings by a preliminary seedling placing unit to prevent the mat-like seedlings placed in a rear end position from moving forward.SOLUTION: The riding type rice transplanter includes three preliminary seedling tables Ca linearly in the front and rear direction, wherein rollers R for smoothly sending a seedling box backward in which the mat-like seedlings are stored. The roller R of the preliminary seedling table Ca in the rear end includes a one-way clutch 43 for preventing a rotation in the direction which prevents the seedling box from moving forward.COPYRIGHT: (C)2013,JPO&INPIT【課題】予備苗載置ユニットでマット状苗の移動を円滑に行わせ、後端位置に載置されるマット状苗の前方への移動を阻止する乗用型田植機を構成する。【解決手段】3つの予備苗載台Caを前後方向に直線状に備え、マット状苗を収容した育苗箱を後方に円滑に送るためのローラRを予備苗載台Caに備えた。後端位置の予備苗載台CaのローラRが、育苗箱の前方への移動を阻止する方向への回転を阻止する一方向クラッチ43を備えている。【選択図】図3
