PROBLEM TO BE SOLVED: To provide a swing rotary type reduction gear that works like the joint-like driving of a person/animal, etc., making compact the size and vanishing the offset quantity of a driving mechanism section in the arm, etc., of a robot by enlarging especially the intersection angle between an input axis and an output axis, regarding the rotating joint device that rotates and transfers the driving of the input axis to the output axis for example.;SOLUTION: This is a swing rotary type revolution coupling 1 composing of: the input axis 3 that is rotatably supported by the body at least; a swing element 4 that is formed to an almost spherical element swung and rotated by the rotation of the input axis; and the output axis 8 driven and rotated engaging to the above swing element.;COPYRIGHT: (C)2004,JPO
