Abstract
A locking structure of a wire rod for a filter element which comprises a support member of either a cylindrical, flat plate or inverted conical shape, a threaded groove helically formed on an outer or inner peripheral surface of the support member, along which groove a wire rod of a desired sectional form is wound, leaving a spiral continuous slit between windings, allowing flow of a fluid to be filtered or separated. Each end portion of the wire rod is bent so as to be merely pushed and firmly secured in a locking hole formed on the support member, without using a locking member such as an insert member or wedge.
