PROBLEM TO BE SOLVED: To suppress progress of abrasion, and increase of driving torque of a driving shaft and an extension rotating body, in a granule feeder.SOLUTION: A granule feeder includes extension rotating bodies 21, 22 provided, on a periphery along a circumferential direction, with a plurality of recesses 40, 50 entered by granules in a storage part, and a driving shaft attached to the periphery in the state where the plurality of extension rotating bodies 21, 22 are aligned in the contact state in the axial center direction. Connection parts 45, 55 for connecting adjusting extension rotating bodies 21, 22 are provided so that the adjusting extension rotating bodies 21, 22 are not separated in the axial center direction from the mutually contact state.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2020,JPO&INPIT【課題】粉粒体供給装置において、摩耗の進展や、駆動軸及び繰り出し回転体の駆動トルクの増大を抑える。【解決手段】貯留部の粉粒体が入り込む複数の凹部４０，５０が、円周方向に沿って外周部に設けられた繰り出し回転体２１，２２と、複数の繰り出し回転体２１，２２が、軸芯方向に並んで接した状態で外周部に取り付けられる駆動軸とが備えられる。隣接する繰り出し回転体２１，２２が互いに接した状態から軸芯方向に離れないように、隣接する繰り出し回転体２１，２２を連結する連結部４５，５５が備えられる。【選択図】図８
