Abstract

A filter medium, which is resiliently expandable in an axial direction and is able to deform the filtration gaps in size in accordance with its expansion, including a compression limiting member for providing required filtration gaps by limiting the amount of compression applied to the filter medium. The filter medium is held by a holder in such a manner that the amount of compression may be adjustable.
