Abstract
When a lid covers an opening portion formed at an upper end of a filter case with a bottomed substantially cylindrical shape inside which a filter element is disposed, the internal space between the lid and the filter case is formed. A bypass flow path connecting the internal space and outside space is formed in the lid, and a relief valve disposed moveably between a position closing the bypass flow path and a position opening the bypass flow path includes an air bleeder formed from a porous material.
