Abstract
A spring is crimpingly fixed to an element holding plate of the fluid filter. Since the spring is crimpingly fixed to the element holding plate a material having a high elastic limit can be freely selected for the spring At the assembling time, the spring can be prevented from yielding to be elastically deformed, even when the size between the upper end of the element and the crest of the filter case fluctuates. As a result, it is possible to provide a fluid filter which requires no high sizing accuracy of the individual parts composing the fluid filter at the assembling time so that it can be easily assembled.
