PROBLEM TO BE SOLVED: To efficiently cool a bearing of a rotary member in a device including the rotary member.SOLUTION: A rotary bearing cooling structure for cooling a bearing of a rotary member includes a bearing 60 rotatably supporting a shaft of a stirring conveying member 55Ya, and a retaining ring 100 disposed on an end side of the shaft with respect to the bearing 60, and restricting axial movement of the stirring conveying member 55Ya. The retaining ring 100 has a blade portion 103 generating air flow by rotating in accompany with rotation of the stirring conveying member 55Ya, and the air flow generated by the rotation of the retaining ring 100, passes through a space facing the bearing 60. 【課題】回転部材を含む装置における回転部材の軸受の冷却をより効率的に行うこと。【解決手段】回転部材の軸受を冷却するための回転軸受冷却構造であって、撹拌搬送部材５５Ｙａの軸を回転自在に支持する軸受６０と、軸受６０よりも軸の端部側に設けられ、撹拌搬送部材５５Ｙａの軸方向への移動を規制する止め輪１００とを含み、止め輪１００は、撹拌搬送部材５５Ｙａの回転に伴って回転することにより気流を発生させる羽部１０３を有し、止め輪１００の回転によって発生する気流が軸受６０に面した空間を通るように構成されたことを特徴とする。【選択図】図５
