PROBLEM TO BE SOLVED: To provide a manufacturing method for a bar handle, which enables highly accurate processing while minimizing a manufacturing cost and to provide a bar handle.SOLUTION: A manufacturing method for a bar handle 1 having a columnar or cylindrical shape and comprising a pair of grip parts 2 at both ends in a longitudinal direction thereof and a clamp part 3 clamped by a clamping part 20 of a vehicle body substantially in the middle thereof in the longitudinal direction thereof, comprises: swaging a handle material 10 of the bar handle 1, thereby forming each grip part 2 so as to give the grip part a first outside diameter d1, forming the clamp part 3 so as to give the clamp part a second outside diameter d2 larger than the first outside diameter d1, and forming a tapering part 4 so as to gradually increase in diameter between each grip part 2 and the clamp part 3.SELECTED DRAWING: Figure 3
【課題】製造コストを抑えながら、高精度に加工できるバーハンドルの製造方法およびバーハンドルを提供する。【解決手段】円柱形状又は円筒形状を有し、長手方向の両端に一対のグリップ部2及び長手方向の略中央に車両本体の挟持部20にクランプされるクランプ部3を備えるバーハンドル1の製造方法であって、バーハンドル1のハンドル素材10をスウェージング加工することにより、グリップ部2を第1外径d1に形成し、クランプ部3を第1外径d1より外径寸法の大きい第2外径d2に形成し、且つグリップ部2とクランプ部3との間を徐々に拡径するテーパ部4に形成する。【選択図】図3
