PROBLEM TO BE SOLVED: To obtain a transmission structure to a granule supply device by properly disposing two one-way clutches in a paddy working machine.SOLUTION: A transmission shaft 47 for transmitting power to a feeding-out unit 35 is disposed to the left and right directions, and a first one-way clutch 51 is mounted to the transmission shaft 47, and thereby a drive member 49 is connected to a drive arm 51a of the first one-way clutch 51. The feeding-out unit 35 is included in the left and right one side with respect to the first one-way clutch 51. There are included a second one-way clutch 52 mounted to the transmission shaft 47 in the left and right other side with respect to the first one-way clutch 51, and transmission mechanisms 50, 53, 54 for converting the backward operation of the drive member 49 into a reverse direction and transmitting it to the second one-way clutch 52 as forward operation of the drive member 49.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2017,JPO&INPIT【課題】水田作業機において、2個のワンウェイクラッチ等を適切に配置して、粉粒体供給装置への伝動構造を得る。【解決手段】繰り出し部35に動力を伝達する伝動軸47を左右方向に配置し、伝動軸47に第1ワンウェイクラッチ51を取り付けて、第1ワンウェイクラッチ51の駆動アーム51aに駆動部材49を接続する。第1ワンウェイクラッチ51に対して左右一方側に繰り出し部35を備える。第1ワンウェイクラッチ51に対して左右他方側に、伝動軸47に取り付けられた第2ワンウェイクラッチ52と、駆動部材49の復路作動を逆方向に変換して駆動部材49の往路作動として第2ワンウェイクラッチ52に伝達する伝動機構50,53,54とを備える。【選択図】図6
