Patent ID: 8539675

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