Abstract
A method for manufacturing a stabilizer bar for a vehicle includes cutting a stabilizer bar material having a round bar-shaped configuration, heating both end portions of the cut stabilizer bar material to be formed as leg bars of the stabilizer bar, rolling both side surfaces of each of both heated end portions of the stabilizer bar material so that both side surfaces are tapered, rotating the stabilizer bar material about an axis thereof between rollers to taper both remaining non-rolled side surfaces of each of both end portions of the stabilizer bar material to be formed as the leg bars of the stabilizer bar, so that each or both end portions of the stabilizer bar material has an elliptical cross-section, forming eyes on distal ends of the stabilizer bar material, and bending the stabilizer bar material into the shape of the stabilizer bar.
