PROBLEM TO BE SOLVED: To improve operability and safety, improve traveling performance and planting performance, and reduce the cost in a walking type rice transplanter.SOLUTION: The walking type rice transplanter includes: left/right wheels respective left/right traveling transmission cases supporting the wheels at a rear end and turning vertically respective left/right arms turning integrally with the traveling transmission cases a relay link member (18) that moves in the cross direction by following the cross-directional movement of a cylinder rod (17) of a lifting/lowering cylinder (16) and respective left/right connection rods (20) for connecting both left/right ends of the relay link member (18) and the arms. The relay link member (18) turns about a vertical fulcrum shaft (19) disposed between the left/right connection rods (20), and an elastic member (80) is provided separately from the relay link member (18), for connecting the left/right connection rods (20).COPYRIGHT: (C)2014,JPO&INPIT【課題】 歩行型田植機において、操作性及び安全性の向上を図り、走行性能及び植付性能を向上させ、コストダウンを図ることを課題とする。【解決手段】 左右の車輪と、該車輪を後端部に支持して上下方向に回動する左右各々の走行伝動ケースと、該走行伝動ケースと一体で回動する左右各々のアームと、昇降シリンダ(16)のシリンダロッド(17)の前後方向の移動に追従して前後に移動する中継リンク部材(18)と、該中継リンク部材(18)の左右両端と前記アームの間を連結する左右各々の連結ロッド(20)を設け、中継リンク部材(18)は左右の連結ロッド(20)の間に配置した上下方向の支点軸(19)を中心に回動自在に構成し、中継リンク部材(18)とは別に左右の連結ロッド(20)を繋ぐ弾性部材(80)を設けた。【選択図】図4
