PROBLEM TO BE SOLVED: To simplify a maintenance structure of a delivery part in a paddy field mobile vehicle having a storage part for storing particulate matters and the delivery part for delivering and supplying the particulate matters from the storage part to a paddy surface.SOLUTION: A paddy field mobile vehicle comprises a first frame 61 which is positioned on a front side or a rear side of a storage part 12 and arranged in a right and left direction, and a second frame 62 which is connected to the first frame 61 and arranged in a front and rear direction, which are provided on a storage part frame 53 supporting the storage part 12. The storage part frame 53 is oscillated around a horizontal axial core P1 in the right and left direction, and thereby the storage part 12 is movably supported by the storage part frame 53 between a work position where a lower part of the storage part 12 is connected to an upper part of the delivery part 13 and a non-work position A2 where the lower part of the storage part 12 is separated from the upper part of the delivery part 13 and where the storage part 12 is separated to the upper side from the delivery part 13.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2018,JPO&INPIT【課題】粉粒体を貯留する貯留部、及び貯留部から粉粒体を繰り出して田面に供給する繰り出し部を備えた水田作業車において、繰り出し部のメンテナンス構造の簡素化を図る。【解決手段】貯留部１２を支持する貯留部フレーム５３において、貯留部１２の前側又は後側に位置して左右方向に配置された第１フレーム６１と、第１フレーム６１に連結されて前後方向に配置された第２フレーム６２とを備える。貯留部フレーム５３を左右方向の横軸芯Ｐ１周りに揺動させることにより、貯留部１２の下部が繰り出し部１３の上部に接続された作業位置と、貯留部１２の下部が繰り出し部１３の上部から分離して貯留部１２が繰り出し部１３から上側に離れた非作業位置Ａ２とに亘って、貯留部１２を貯留部フレーム５３により移動自在に支持する。【選択図】図７
