Abstract
A filter device includes a bag-shape filter body. The filter device is attached in a manner such that an internal space of the filter body connects through to a fuel intake port in a fuel tank. The filter body includes two or more filter materials overlaying each other. At least one of the filter materials is configured so that a cross sectional area of its fuel passage is different between a primary side and a secondary side of the filter material so as to be a multifunctional filter material having a function of gradually capturing dust having different particle sizes.
