Description

また、本実施形態では、螺旋状の凸部３４のうちの最も内周半径が大きい部位の内周半径（ＣＩＤｍａｘ）が、先端チップ２１のうちの最も外周半径が大きい部位の外周半径（ＴＯＤｍａｘ）よりも大きくなるように形成されている。具体的には、例えば、上述した中空シャフト１４のテーパ部１４１における基端の外径が第３の実施形態のテーパ部１３１よりも更に大きくなるように形成（図５参照）することで、第２のコイル体３４Ｃの内周半径（ＣＩＤｍａｘ）が、先端チップ２１の外周半径（ＴＯＤｍａｘ）よりも大きくなるようにしてもよい。内周半径（ＣＩＤｍａｘ）となる螺旋状の凸部３４の部位は、テーパ部１４１上の部位であってもよく（不図示）、本体部１４２上の部位であってもよい（図５参照）。
