Abstract

　本発明の一実施形態では、ウォーターポンプ（１０）は、エンジンの回転が伝達される駆動側回転体（２０）から、ポンプインペラ（３１）が設けられる従動側回転体（３０）への回転の伝達が非接触の状態で行われるように構成される。駆動側回転体（２０）には、負圧室（５０）と、異なる極性同士が互いに向き合うように設けられる一対の永久磁石（２６ａ，２６ｂ）とが備えられる。従動側回転体（３０）には、一対の永久磁石（２６ａ，２６ｂ）の間に所定の間隔を隔てて設けられる誘導部（３２ｂ）を有する誘導リング（３２）が備えられる。そして、負圧室（５０）に導入する負圧によって、一対の永久磁石（２６ａ，２６ｂ）を誘導部（３２ｂ）に対し回転軸方向に移動させて、一対の永久磁石（２６ａ，２６ｂ）および誘導部（３２ｂ）の回転軸方向のオーバーラップ量（Ｌ１）を変更する。
