PROBLEM TO BE SOLVED: To provide a harvester in which a change is not generated in a flow of a harvested material from a harvesting unit to a feeder regardless of tension operation of an endless turning carrier by a tension mechanism.SOLUTION: A feeder 6 includes a starting-edge side rotating wheel 23 provided at the conveyance starting-edge side of a feeder case 20, and left and right endless turning carriers 21 wound around a termination side rotating wheel 24 provided at the conveyance terminal side of the feeder case 20 in a turning/driving manner. One or both of the starting-edge side rotating wheel 23 or the termination side rotating wheel 24 include a drive shaft 24a, and left and right sprockets 24b where the left and right endless turning carriers 21 are wound. A cylindrical cover 63 is externally fitted in a place positioned between the left and right sprockets 24b of the drive shaft 24a in a relatively rotatable manner, and an arm 64 is extended from the cover 63. The arm 64 is configured in a reinforcing member 70 laterally bridged to the feeder case 20 in an engaging manner.SELECTED DRAWING: Figure 4【課題】テンション機構による無端回動搬送体の張り操作にかかわらず、収穫部からフィーダへの収穫物の流れに変化が生じない収穫機を提供する。【解決手段】フィーダ６は、フィーダケース２０の搬送始端側に設けられた始端側回転輪体２３と、フィーダケース２０の搬送終端側に設けられた終端側回転輪体２４とに回動駆動可能に巻回された左右の無端回動搬送体２１と、を備え、始端側回転輪体２３又は前記終端側回転輪体２４の一方又はその両方が、駆動軸２４ａと、左右の無端回動搬送体２１が巻回される左右のスプロケット２４ｂとを備え、駆動軸２４ａのうち、左右のスプロケット２４ｂの間に位置する箇所に筒状のカバー６３が相対回転可能に外嵌されると共に、カバー６３からアーム６４が延出され、アーム６４は、フィーダケース２０に横架された補強部材７０に係合可能に構成されている。【選択図】図４
