Patent ID: 11370109

Abstract:
An industrial robot includes: a first-member and a second-member that are rotatable about a particular axis and that each have a hollow portion extending along the axis; a cylindrical member inserted into the hollow portions along the axis, and fixed to the first-member; and a wire disposed in a cylindrical gap between the cylindrical member, the first-member, and the second-member, the wire having a length that enables rotation between the first-member and the second-member and having one end fixed to the first-member and another end fixed to the second-member. The second-member includes a first-portion rotatably supported by the first-member, a second-portion that fixes the end of the wire, and a third portion serially connected between the second-portion and the first-portion, and the third portion has an inner circumferential surface that faces the gap and has been subjected to a friction reducing process.
