To achieve a relative rotation of a pipe part at a relatively large angle without significantly changing a process of a cable.SOLUTION: A connection structure is used to connect a first member with a second member, and the first member and the second member are pivoted to each other to rotate around a rotational axial center relative to each other. The connection structure includes: a first joint member permanently connected to the first member; and a second joint member permanently connected to the second member and connected to the first joint member so as to rotate around the rotational axial center. The second joint member includes: a rotational surface substantially vertical to the rotational axial center; and a first position restriction part and a second position restriction part respectively projecting along a parallel direction to the rotational axial center from the rotational surface and positioned on both sides of the rotational axial center. The connection structure further includes at least one transmission member, which extends into the first member and the second member to be projected and penetrates through the connection structure from between the first position restriction part and the second position restriction part, thereby flexibly bending according to the rotation between the first member and the second member.SELECTED DRAWING: Figure 6
【課題】ケーブルの行程を著しく変化させずに管部を比較的大きな角度で相対回転させること。【解決手段】連結構造は、第一部材と第二部材とを連結することに用いられ、第一部材と第二部材とは互いに枢着されて回転軸線を中心に互いに対して回転する。連結構造は、第一部材に固定的に連結される第一継手部材と、第二部材に固定的に連結され、回転軸線を中心に第一継手部材に回転可能に連結される第二継手部材と、を含み、第二継手部材は、回転軸線に対して略垂直な回転面と、回転面から回転軸線に平行な方向に沿ってそれぞれ突起し、回転軸線の両側に位置する第一位置制限部及び第二位置制限部と、を含む。連結構造はさらに少なくとも一つの伝動部材を含み、それは第一部材及び第二部材の中に延伸して穿設され、第一位置制限部と第二位置制限部との間から連結構造を貫通し、それにより第一部材と第二部材との間の回転に応じて柔軟に曲がることができる。【選択図】図6
