PROBLEM TO BE SOLVED: To provide a grain stalk raising unit that can be manufactured at a low cost with a reduction in number of parts by eliminating the need of a conventional independent guide rail.SOLUTION: A grain stalk raising unit (8) includes a front raising case (20a) on the front side and a rear raising case (20b) on the rear side that form a case of the grain stalk raising unit (8) a raising chain (22) mounted in the case and having a raising lug (21) and a driving sprocket (24) and a driven wheel body (25) around which athe raising chain (22) is wound. The front raising case (20a) and the rear raising case (20b) joined facing in front and in the rear are formed with bending guide parts (23) bending mutually facing surfaces into recessed shape at a portion on the raising path side where the raising lug (21) is allowed to stand up, and coming in sliding contact with a sliding part (21a) formed at the base of the raising lug (21) to guide the raising lug (21) upward while holding the raising lug (21) in a standing-up attitude.COPYRIGHT: (C)2014,JPO&INPIT【課題】穀稈引起し装置において従来のような別体のガイドレールを不用とし、部品点数を削減して安価に製造できるものとする。【解決手段】穀稈引起し装置(8)のケースを形成する前側の前引起しケース(20a)および後側の後引起しケース(20b)と、ケース内に内装される引起しラグ(21)を備えた引起しチェン(22)と、引起しチェン(22)を巻回する駆動スプロケット(24)および従動輪体(25)から構成された穀稈引起し装置(8)において、前後に対向して接合される前引起しケース(20a)と後引起しケース(20b)には、引起しラグ(21)を起立させる引起し経路側の部位において互いに対向する面を凹状に屈曲させて、引起しラグ(21)の基部に形成された摺動部(21a)に摺接して引起しラグ(21)を起立姿勢に保持したまま上昇案内する屈曲ガイド部(23)を形成する。【選択図】 図5
