PROBLEM TO BE SOLVED: To enable three-spindle rotation, and to secure load-resistant or smooth rotation.SOLUTION: A multi-spindle rotation structure 1 comprises: a cylindrical body 10 having an outer peripheral surface 11; an annular body 30 having an outer peripheral surface 31 consisting of a predetermined width with right and left parts of the spherical surface CA cut symmetrically to be fitted externally on the cylindrical body in a concentric form via a bearing 40; a support body 20 the attachment part 22 of which is anchored on the side face 12 of the cylindrical body to make the axial center part 21 coupled with the attachment part extend on the intermediate plane in the width direction of the annular body and outwardly in a radial direction; and a pair of rotation bodies 50, which are rotation bodies each having a rotary shaft 51 supported by both side faces of the cylindrical body, the rotary shaft being orthogonal to the axial direction of the axial center part and the axial center direction of the annular body, and the radius R of the rotation body in the axial direction of the outer peripheral surface being set to a size upon radial descent from the rotary shaft of the rotation body, onto the circumference CPo including a predetermined singular point Po out of a rotation locus the outer peripheral surface of the annular body forms when the annular body rotates around the axial center part.SELECTED DRAWING: Figure 3

    【課題】3軸周りの回転を可能にし、かつ耐荷重性、乃至は滑らかな回転を確保する。【解決手段】多軸回転構造体1は、外周面11を有する円柱体10と、球面CAの左右部位が対称に切断された、所定幅からなる環状の外周面31を有し、軸受40を介して円柱体に同心状に外嵌された円環体30と、取付部22が円柱体の側面12に固設され、取付部に連結された軸心部21が円環体の幅方向中間の平面上で、かつ径方向外方に延びた支持体20と、円柱体の両側面にそれぞれ軸支された回転軸51を有する一対の回転体50であって、回転軸は軸心部の軸方向及び円環体の軸心方向と直交し、回転体の外周面の軸方向における半径Rは、円環体が軸心部周りに回転したときに円環体の外周面が形成する回転軌跡の内、所定の特異点Poを含む円周CPo上まで、回転体の回転軸から径方向に下ろした寸法に設定された回転体とを含む。【選択図】図3
