摘要： In a fluid pump device, a filter is secured to a housing. A meshed portion of the filter substantially covers an inlet opening of the housing. Each engaging projection of the filter is engaged with a corresponding engaging recess of the housing in a direction perpendicular to an axial direction of an impeller. Arm portions of the filter substantially perpendicularly extend with respect to a meshed portion of the filter and are resiliently flexible in the direction perpendicular to the axial direction of the impeller. Each coupling projection of the filter is provided between adjacent two arm portions of the filter and is engaged with a corresponding coupling recess of the housing in the axial direction of the impeller.
