Abstract

　インペラ２２は、上部軸受け９と下部軸受け１０により上下端で回転自在に支持された回転軸７と、複数のベーン６と、ベーンの内周側を回転軸に結合するアーム１８と、各ベーンの外周側に連結された環状連結部８と、環状連結部の下部に配置された従動磁石部１２とを有する。ロータ１３に設けられた駆動磁石部１６と従動磁石部１２とが、ハウジングの底部壁を挟んで対向し、磁気結合を介してロータの回転がインペラに伝達される。ベーンの下方に封鎖部材２３が配置され、回転軸と環状連結部の間に亘る領域の空間を、少なくとも回転軸の周囲に開口部２４を残して封鎖している。インペラの回転軸が上下の軸受けで支持され、ベーンの外周縁部の下部が環状連結部により連結された構造において、下部軸受けの近傍における血栓の形成を抑制することができる。
