Description
図1から図3は、本発明に係る投竿の一実施形態を示す図であり、図1は全体構成を示す図、図2は穂先竿杆の部分を示す図、そして、図3は穂先竿杆の主要部の構成を拡大して示す図である。
以下、穂先竿杆10の構成について、図2及び図3を参照して説明する。
上記した穂先竿杆10は、常法に従い、マンドレル50にプリプレグシートを巻回し、これを熱硬化し、マンドレルを脱芯することで製造される。本発明では、このような製造方法を実施するに際して、マンドレル50の先端に小径部51を形成しておき、この部分に穂先竿杆10を成形するプリプレグシート15よりも高比重となる金属製の管状体(高比重材20)を嵌入し、その上から管状体よりも低比重となるプリプレグシート15を巻回する。この場合、金属製の管状体は、小径部51に嵌入されると、その外周面は、マンドレル50の外周面と面一になるように形成されている。そのため、外周に、強化繊維が軸長方向に配向したプリプレグシートを巻回した際に強化繊維が折れ曲がることなく(応力集中が防止される)、安定した状態で繊維強化樹脂層を形成することができる。
また、本発明に係る投竿は、仕掛けを遠投するものに限らず、仕掛けを投擲して釣糸にテンションを与えて魚の当たりを待つ各種の釣竿に適用される。

Claims (8)
- 繊維強化樹脂材によって管状に形成された穂先竿杆を有する投竿において、
前記穂先竿杆の先端領域に、前記穂先竿杆を構成する材料に対して比重が3〜6倍の高比重材を配設し、
前記高比重材は、前記穂先竿杆の先端領域の内周面に取着され、穂先竿杆全長の5〜25%の範囲の長さの金属製の管状体であり、
