Abstract
A filter adapted for use in a fluid passage and having a novel structure for coupling to the fluid passage. The filter has a general configuration of a bottom-ended cylinder, with the bottom portion formed with a plurality of bores constituting a filtrating screen. The cylinder has an annular joining projection at an end remote from the filtrating screeen, the projection being securely elastically fitted on the outer circumferential surface of a restriction fixed to the fluid passage or on the inner surface of the fluid passage, securely and airtightly coupled to each other. The filter is positioned close to the constriction of the fluid passage, the risk of accumulation of alien matter therebetween being eliminated. Also, the entire cylindrical filter is made from an integral molding of elastic material, there being no likelihood of adverse effect by the fibers that constitute the filter.
