To provide a sealing mechanism capable of elongating durability life of a sealing function.SOLUTION: A sealing mechanism includes: a rotating shaft 110; a driving source 120 for rotating the rotating shaft 110; a case 130 for storing the driving source 120; a sealing device 200 for sealing an annular gap between the rotating shaft 110 and the case 130; and an impeller 300 rotated with the rotating shaft 110, and generating a flow so that fluid in the vicinity of a sliding portion between the sealing device 200 and at least one of the rotating shaft 110 and the case 130 flows toward a direction separating from the sliding portion.SELECTED DRAWING: Figure 1

    【課題】密封機能の耐久寿命を延ばすことのできる密封機構を提供する。【解決手段】回転軸110と、回転軸110を回転させる駆動源120と、駆動源120を収容するケース130と、回転軸110とケース130との間の環状隙間を封止する密封装置200と、回転軸110と共に回転し、密封装置200と回転軸110及びケース130のうちの少なくともいずれか一方との摺動部付近の流体が該摺動部から遠ざかる方向に向かって流れる流れを生じさせるインペラ300と、を備えることを特徴とする。【選択図】図1
