Abstract

　簡素な構成で、ロータとポンプ室との隙間を精度良く調整可能にすることを課題とする。ルーツ式ポンプ（１）のケーシング（２）が、回転軸（Ａ１，Ａ２）の軸方向に沿って分割された第１ケーシング（３）と第２ケーシング（４）を有し、第１ケーシング（３）および第２ケーシング（４）が、それぞれ、回転軸（Ａ１，Ａ２）を支持する軸受（６６，６７，７１，７２）を支持する軸受支持部（４６ａ，４７ａ，４６ｂ，４７ｂ）と回転軸（Ａ１，Ａ２）に設けられたロータ（Ｒ１～Ｒ６）が収容されるロータ収容空間（Ｐ１ａ～Ｐ６ａ，Ｐ１ｂ～Ｐ６ｂ）とを有する。したがって、一方のケーシング（３，４）に支持されてロータ（Ｒ１～Ｒ６）が外部に露出した状態で、全てのロータ（Ｒ１～Ｒ６）とポンプ室の一部を構成するロータ収容空間（Ｐ１ａ～Ｐ６ａ，Ｐ１ｂ～Ｐ６ｂ）との隙間を測定できるため、隙間を精度良く調整できる。
