PROBLEM TO BE SOLVED: To improve easiness in assembling work for a transmission case of a rice transplanter and increase a strength of component elements of the rice transplanter.SOLUTION: A rice transplanter of this invention is constituted such that a power from an engine 8 is changed through a hydraulic continuously variable transmission 24 and transmitted from an output shaft 58 of the hydraulic continuously variable transmission 24 to a PTO transmission shaft 62 and a travel transmission shaft 63 through a travel transmission shaft 60. Each of the shafts 58, 60, 62 and 63 is stored in a transmission case 9. The transmission case 9 is provided with a main body 9a having a deep depth and a shallow lid part 9b covering the main body part. Each of the shafts 58, 60, 62 and 63 is arranged under an attitude in which it crosses with the openings of the main body part 9a and the lid part 9b. An intermediate plate 80 rotatably supporting each of the shafts 58, 60, 62 and 63 is removably attached in the main body part 9a of the transmission case 9.COPYRIGHT: (C)2014,JPO&INPIT【課題】田植機において、ミッションケースの組立ての容易性向上や部材の強度アップ等を図る。【手段】本願発明の田植機は、エンジン8からの動力を油圧無段変速機24で変速して、油圧無段変速機24の出力軸58から走行変速軸60を介してPTO伝動軸62及び走行伝動軸63に伝達するように構成する。各軸58,60,62,63をミッションケース8内に収容する。ミッションケース8は、深さが深い本体部9aとこれを覆う浅い蓋部9bとを備える。各軸58,60,62,63は本体部9a及び蓋部9bの開口面と交差した姿勢に配置する。ミッションケース9の本体部9a内に、各軸58,60,62,63を回転可能に支持する中間プレート80を着脱可能に固定する。【選択図】図28
