PROBLEM TO BE SOLVED: To provide a production method of a rack housing which enables production of a weight-saved rack housing in a short time while suppressing occurrence of troubles in molding and a rack housing produced by the method.SOLUTION: A production method of a rack housing comprises setting two laminate sheets 37, in a heated state, formed by laminating a carbon fiber sheet and a film of a thermoplastic resin together, in a region of a die 38 corresponding to a cylindrical part 13 of a rack housing, clamping the die 38 to impregnate the carbon fiber sheet with the thermoplastic resin of the film, pressing the laminated sheets 37 individually into semi-cylindrical bodies 17 which correspond to a half of the circumference of the cylindrical part 13 and have connection parts 16 at both ends, in the circumferential direction S, of the semi-cylindrical bodies 17 and joining both the semi-cylindrical bodies 17 mutually in the individual connection parts 16 to form a cylindrical part 13.

    【課題】軽量化されたラックハウジングを、成形時の不具合の発生を抑制しつつ短時間で製造できる製造方法と、かかる製造方法によって製造されたラックハウジングとを提供すること。【解決手段】金型38においてラックハウジングの筒部13に対応する領域に、炭素繊維シートと熱可塑性樹脂のフィルムとを積層して構成された2枚の積層シート37を、加熱された状態でセットする。そして、金型38を型締めして、炭素繊維シートにフィルムの熱可塑性樹脂を含浸させ、2枚の積層シート37のそれぞれを、筒部13の半周分の半筒体17と、半筒体17の周方向Sの両端の接続部16とを有する形状にプレス加工するとともに、両半筒体17をそれぞれの接続部16同士で結合させて筒部13を形成する。【選択図】図5
