Abstract
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.

A fuel pump module comprising:
- a suction filter removing a foreign material included in fuel supplied from a fuel tank to an internal combustion engine;
- a fuel pump portion raising a pressure of fuel in the suction filter and discharging the fuel to the internal combustion engine, wherein the fuel pump portion has an end part opposing the suction filter, and a convex part protruding toward the suction filter is defined at the end part;
- a pump case housing the fuel pump portion;
- 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, wherein
- the holding member is positioned between the fuel pump portion and the suction filter,
- the holding member 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, and
- the convex part has a tip part capable to be in contact with the concave part in the axis direction.
