Claims (3)
- 内視鏡に配置された軸部材の外周部に雄ねじ部が形成されると共に、連結相手部材に形成された連結孔に上記軸部材が通されて、上記雄ねじ部と螺合して上記連結相手部材と互いに重なり合うナット状部材により、上記連結相手部材が上記軸部材に固定された内視鏡における連結部の構造において、
上記連結相手部材には、上記ナット状部材が緩く嵌め込まれる凹部が形成されてその凹部内に上記ナット状部材が配置されると共に、ねじ孔が、上記連結相手部材の外周から内方の上記ナット状部材の外周に向かって上記軸部材の軸線位置に対し偏位する向きであって上記雄ねじ部と螺合する上記ナット状部材を上記連結相手部材との重なり合い面側に螺動させる方向に形成され、
上記ナット状部材が、上記ねじ孔に螺合する固定ねじで上記軸部材の軸線周り方向に押圧されることにより上記連結相手部材と圧接させられて上記連結相手部材に対し固定され、それによって上記連結相手部材が上記軸部材に固定されていることを特徴とする内視鏡における連結部の構造。 - 上記雄ねじ部に隣接して上記軸部材に略多角形状の角軸部が形成されると共に、上記連結相手部材の連結孔が上記角軸部と嵌まり合う略多角形状に形成されて、上記連結相手部材が、上記角軸部の端部に形成された段差部に上記ナット状部材で押し付けられて上記軸部材に固定されている請求項1記載の内視鏡における連結部の構造。
- 上記連結相手部材に形成された連結孔に上記雄ねじ部と螺合する雌ねじが形成されていて、上記連結相手部材と上記ナット状部材の双方が上記軸部材の雄ねじ部と螺合している請求項1記載の内視鏡における連結部の構造。
