Description
まず、図3に示すような、押出形材(素管)40を、例えば、押出成形により成形する。
次に、成形工程によって得られた押出形材40を切断する。具体的には、図3に示すように、管部41Aに、X方向に交差する方向に延びて、連結部42に達する第1切込43を設けるように、管部41Aを切断する。同様に、管部41Bに、第1切込43とはX方向の位置が異なる位置に、X方向に交差する方向に延びて、連結部42に達する第2切込44を設けるように、管部41Bを切断する。その後、第1切込43の端部43aと第2切込44の端部44aとの間を連結する第3切込45を形成するように、連結部42をX方向に沿って切断する。第1切込43、第2切込44、及び第3切込45を形成することで、押出形材40は2つの長尺中空部材50に分離される。ここで、第3切込45のX方向中心と第1切込43の端部43aとの間の距離は、第3切込45のX方向中心と第2切込44の端部44aとの間の距離と等しい。すなわち、押出形材40は、第3切込45のX方向中心を通り、Y方向に延びた中心軸C3に対して2回対称となるように切断される。
その後、長尺中空部材50と両端支持ブラケット20、支持ブラケット21及びステアリングブラケット22とを接合する。具体的には、図1に示すように、長尺中空部材50を取り囲むように両端支持ブラケット20,支持ブラケット21,及びステアリングブラケット22を配置させる。この状態で第1管部51及び第2管部52を拡管することにより、長尺中空部材50と両端支持ブラケット20及び支持ブラケット21をかしめ接合する。また、長尺中空部材50とステアリングブラケット22とを溶接接合する。
