PROBLEM TO BE SOLVED: To provide a reaper more reducing a burden on a worker when attaching a chip receiver.SOLUTION: The reaper includes a blade 2 extending in a longitudinal direction, a blade supporting part supporting the blade 2, a chip receiver 3 detachably and slidingly attached to a supporting beam 12 of the blade supporting part in a longitudinal direction, and a holding mechanism for holding the chip receiver 3 on the blade supporting part. The holding mechanism is provided with an elastic deformation part 43 which is not elastically deformed in a prescribed zone from a slide-starting point and is elastically deformed when passing over through the prescribed zone so as to increase friction resistance to sliding movement when the chip receiver 3 is slidably attached.COPYRIGHT: (C)2013,JPO&INPIT【課題】チップレシーバを装着する際の作業者の負担をより一層軽減することができる刈取機を提供する。【解決手段】前後方向に伸びる刃物2と、該刃物2を支持する刃物支持部と、該刃物支持部の支持梁12に前後方向に着脱自在にスライド装着されるチップレシーバ3とを備えた刈取機であって、チップレシーバ3を刃物支持部に保持するための保持機構を備え、該保持機構は、チップレシーバ3のスライド装着時にスライド開始点から所定区間内は弾性変形せず該所定区間を過ぎると弾性変形してスライド移動に対する摩擦抵抗を増大させる弾性変形部43を備えている。【選択図】図8
