<p>The present invention provides a fuel pump with increased concentricity of metal bearings. When a pump part (30) is inserted in a storage section (11a) of a housing (11), the outer periphery of the pump part (30) is held by a plurality of protrusions (11e) disposed in the storage section (11a) of the housing (11), and the intervals between the plurality of protrusions (11e) are uniform in the circumferential direction of the storage section (11a) of the housing (11). Furthermore, each protrusion (11e) is either disposed at the position of teeth of a stator core (9a) when each of the stator cores (9a) is projected in the axial direction, or disposed at a position where the mechanical separation angles with respect to the teeth in the circumferential direction are the same.</p> |
