To provide a pump which enables improvement of reliability of a stator.SOLUTION: One embodiment of a pump of the invention includes: a rotor which may rotate around a center axis; a stator assembly which is positioned at the radial outer side of the rotor and encloses the rotor; a pump part connected to one axial side of the rotor; a support member which is positioned at the radial inner side of the stator assembly and has a rotor housing part which houses the rotor therein; and a resin housing in which the stator assembly and the support member are molded. The rotor housing part has: a lid part which covers the rotor from the other axial side; and a cylindrical part which is positioned between the rotor and the stator assembly in a radial direction and is open to one axial side. The stator assembly has: an annular stator core; multiple coils attached to the stator core; and a stator cover which covers the multiple coils.SELECTED DRAWING: Figure 2 【課題】ステータの信頼性を高めたポンプを提供する。【解決手段】本発明のポンプの一つの態様は、中心軸線を中心として回転可能なロータと、ロータの径方向外側に位置しロータを囲むステータアッシーと、ロータの軸方向一方側に繋がるポンプ部と、ステータアッシーの径方向内側に位置しロータを内部に収容するロータ収容部を有する支持部材と、ステータアッシーおよび支持部材をモールドする樹脂ハウジングと、を備える。ロータ収容部は、ロータを軸方向他方側から覆う蓋部と、径方向においてロータとステータアッシーとの間に位置し、軸方向一方側に開口する筒状部と、を有する。ステータアッシーは、環状のステータコアと、ステータコアに装着される複数のコイルと、複数のコイルを覆うステータカバーと、を有する。【選択図】図２
