摘要： A spring having an enlarged diameter base mountable in the heel of a seal casing to enable flared arms extending forwardly from the base to freely exert by cantilever action an outwardly directed spring bias against the casing while the spring is retained by its base in the casing. A method of making a continuous spring from a single strip of metal to form opposing flared arms extending from an enlarged concave base.
