Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent powder on a shaft seal side from staying, by forming a jetting hole in a hollow shaft in a state corresponding or non-corresponding to a bush provided in a mating ring for partitioning the shaft seal side and a container body side.SOLUTION: A shaft seal structure is provided with: a pipeline (174) or jacket (170) disposed in a hollow shaft (118); and a first jetting hole (172) formed into the shape of the hollow shaft (118), and disposed in a state corresponding or non-corresponding to a bush (145 or 147). In the shaft seal structure, fluid jetted from the pipeline (174) or jacket (170) is jetted toward the bush (145 or 147) through the first jetting hole (172). 【課題】本発明は、軸封側と容器本体側とを分画するためのメイティングリングに設けたブッシュに対応又は非対応状態で中空軸に噴出孔を形成し、軸封側の粉体の滞留を防止することである。【解決手段】本発明による軸封構造は、中空軸(118)内に設けられた配管(174)又はジャケット(170)と、前記中空軸((118)の型に形成され前記ブッシュ(145又は147)に対応又は非対応状態で配設された第１噴出孔(172)を設け、前記配管(174)又はジャケット(170)から噴出された流体は前記第１噴出孔(172)を経てブッシュ(145又は147)側へ噴出するようにした構成である。【選択図】図１
