Beschreibung
Zusammenfassung:	A fuel pump module includes a suction filter, a fuel pump portion having an end part opposing the suction filter, and a holding member allowing the fuel pump portion to rotate around a central axis of the fuel pump portion and restricting the fuel pump portion from moving in an axis direction. A convex part protruding toward the suction filter is defined at the end part of the fuel pump portion. The holding member is positioned between the fuel pump portion and the suction filter and has a concave part, in which the convex part is inserted, such that a clearance is defined between the convex part and the concave part in a radial direction. The convex part has a tip end capable to be in contact with the concave part in the axis direction.
