To provide a mechanical coupling tool that can couple positively to an object having a hollow hole by a simple structure.SOLUTION: A mechanical coupling tool, to be inserted in a hollow hole provided in an object and coupled to the object, comprises a cylindrical insertion part 81 that is to be inserted in a hollow hole provided in an object and has a through-hole 81h passing through between both ends and a shaft member 82 that is rotatably provided inside the insertion part 81. In a side face of the insertion part 81, an opening 81w is formed communicating between interior and exterior of the insertion part 81. The shaft member 82 is provided with a diameter-increased portion 83 eccentric with respect to a rotary axis thereof. In a side face of the diameter-increased portion 83, a linear projection 83p is provided along a circumferential direction of the diameter-increased portion 83, a rotary axis of which is in a state of being eccentric toward an opening 81w of the insertion part 81 with respect to a center axis of the insertion part 81, so that the diameter-increased portion 83 is set up to be arranged in a position corresponding to the opening 81w of the insertion part 81.SELECTED DRAWING: Figure 1

    【課題】簡単な構造で中空な孔を有する物体と確実に連結できる機械式連結器具を提供する。【解決手段】物体に設けられた中空な孔に挿入され、物体に連結される連結器具であって、物体に設けられた中空な中空孔に挿入される、両端間を貫通する貫通孔81hを有する筒状の挿入部81と、挿入部81の内部に回転可能に設けられた軸部材82と、を備えており、挿入部81の側面には、挿入部81の内部と外部とを連通する開口81wが形成されており、軸部材82は、その回転軸に対して偏心した膨径部83が設けられており、膨径部83の側面に膨径部83の周方向に沿って線状突起83pが設けられており、その回転軸が挿入部81の中心軸に対して挿入部81の開口81w側に偏心した状態となり、膨径部83が挿入部81の開口81wと対応する位置に配置されるように配設されている。【選択図】図1
