PROBLEM TO BE SOLVED: Conventionally, when a lug after being pulled up turns around a drive sprocket, there is a problem that a tip of a preceding lug is caught between a mounting base end portion and a chain at the time of turning and mechanically locks. The present invention relates to a grain culm raising device (11) of a combine for raising raised culms by raising a plurality of raising lugs (12), wherein said raising lugs (12) with respect to a raising chain (17). ) Is set to be shorter than the total length (L) of the raising lug (12) with respect to the raising chain (17) from the attachment base end to the leading end, and the raising lug (12) is attached to the raising lug (12). Has a rounded-up portion (23) formed by diagonally rounding up a corner portion on the rising side facing the raising chain (17) at the mounting base end portion. As a result, the base end corner on the lug mounting side is cut up diagonally so that the tip end of the lug is not pinched between the mounting base end and the chain, and mechanical locking is prevented.
