PROBLEM TO BE SOLVED: To provide a movable joint of a levitation type structure, hardly damaged even if large force is added from a wave.SOLUTION: A spherical joint 6 of the present invention is the spherical joint for cushioning force by a wave by rocking a joint part of a levitation type structure, and comprises a spherical socket 61 having an inner chamber 61c and a conical hole 61d, a central ball 62, a spherical stud 63 having a spherical plate 63a and a connection rod 63b, a spherical seat 64 and at least two connection flanges 65 for fixing-supporting the spherical stud 63 and the spherical seat 64. The central ball 62 is formed in a smaller diameter than the inner chamber 61c and a larger diameter than an inner chamber side opening of the conical hole 61d, and an outer peripheral end of the spherical plate 63a of the spherical stud 63 is formed in a circular shape of a larger diameter than the inner chamber side opening of the conical hole 61d.SELECTED DRAWING: Figure 5

    【課題】波から大きな力が加わっても破損しにくい浮揚式構造物の可動継手を提供する。【解決手段】本発明の球面継手6は、浮揚式構造物の継手部を揺動させて波による力を緩衝する球面継手である。内室61c、及び円錐孔61dを有する球形ソケット61と、中心球62と、球面板63a、及び連結桿63bを有する球面スタッド63と、球座64と、球面スタッド63、及び球座64を固定支持する少なくとも2個の連結フランジ65とを備える。中心球62は、内室61cより小径かつ円錐孔61dの内室側開口より大径に形成され、球面スタッド63の球面板63aの外周端は、円錐孔61dの内室側開口より大径の円形に形成されている。【選択図】図5
