Claim:
A retainer for fixing terminals of springs to a seat frame for a seat, wherein said seat frame comprises a pair of spaced apart side frame sections which are opposed to each other; said side frame sections having first and second end portions; a first intermediate frame section interconnecting said first end portions of said side frame sections; and a second intermediate frame section interconnecting said second end portions of said side frame sections and opposed to said first intermediate frame section; at least one of said side frame sections and said first and second intermediate frame sections being formed from a round shaft; said springs having first and second terminals; said first terminals being adapted to be fixed to one of said side frame sections and said first and second intermediate frame sections which is opposed to said round shaft; said second terminals being each formed into a substantially U-shape in outline and comprising first and second spaced apart axial portions and an intermediate axial portion interconnecting said first and second axial portions; said retainer comprising: a longitudinal body of a substantially U-shape in cross-section, and pairs of first and second spring-engaging pieces provided at said U-shaped longitudinal body; said first spring-engaging pieces being bent laterally from one edge of said substantially U-shaped body and perpendicularly to said U-shaped body from the one edge of said substantially U-shaped body for engaging with said first axial portions; said second spring-engaging pieces being bent into substantially U-shapes laterally from the other edge of said substantially U-shaped body for engaging with said second axial portions; and said substantially U-shaped body being adapted to be mounted on said round shaft with an opening side thereof facing downwardly, with said first spring-engaging pieces being located inside said seat frame and with said second spring-engaging pieces being located outside said seat frame; whereby said retainer is adapted for retaining said second terminals of said springs to said round shaft such that said intermediate axial portions can be located under said round shaft and engaged with said round shaft.
