ABSTRACT:
A filter is annularly attached around a peripheral wall of a housing. The filter is composed of a filtering element that covers a fluid passage for inhibiting foreign objects from entering, a supporting portion for supporting the filtering element, and a connecting portion for connecting between both ends of the supporting portion. The connecting portion is narrower than the supporting portion. The filter is movable radially in two directions according to a clearance between the filter and the housing. A contact portion is formed, with being able to be slid within a movable range of the filter, between an outer surface portion of the peripheral wall that surrounds an opening of the fluid passage and an inner surface portion of the filter that surrounds the filtering element.
