以下、上記実施形態から変更可能な他の実施形態を簡単に説明する。
(1)実施形態では、筒状体として緩衝装置のアウターケースを開示しているが、これに限らず、筒状をなした部材であれば種類を問わない。
(2)実施形態では、炭素繊維と熱可塑性樹脂成分とを混繊した混繊糸を組紐状に編み込んで形成しているが、これに限らず、混繊糸を不織布状に絡み合わせて筒状体を形成しても良い。また、混繊糸を組んだり、織ったり、編んだりして筒状体を形成しても良い。
(3)実施形態では、熱可塑性樹脂、及び熱可塑性樹脂成分にポリアミド樹脂を用いているが、これに限らず、熱可塑性樹脂、及び熱可塑性樹脂成分に他の熱可塑性樹脂を用いても良く、これら樹脂を複合的に用いても良い。
(4)実施形態では、被覆材にステンレスを用いているが、これに限らず、被覆材に他の金属を用いても良い。
(5)実施形態では、連続強化繊維に炭素繊維を用いているが、これに限らず、連続強化繊維にガラス(glass)繊維やアラミド(aramid)繊維等の他の繊維を用いても良く、これら繊維を複合的に用いても良い。
(6)実施形態では、第1金具を設けているが、これに限らず、第1金具を設けなくても良く、第1金具が設けられる空間に熱可塑性樹脂や連続強化繊維等を充填して形成しても良い。
(7)実施形態では、筒状体の周方向に設けられるばね受け部、及びナックルブラケットを凹凸の例示としてあげているが、周方向に限らず、筒状体の軸方向に凹凸を形成してもよい。筒状体の軸方向に設けられる凹凸として取り付けアイを形成してもよい。
