PURPOSE: A joint-type robot wrist is provided to minimize distortion and bending stress actuated on a cable during the operation of a robot wrist. CONSTITUTION: A joint-type robot wrist(10) comprises first, second, and third bodies(12,14,16). A first end portion(12') of the first body is installed in a robot element capable of rotating around a first axis(IV). A first end portion(14') of the second body is installed in a second end portion(32) of the first body to be rotated around a second axis(V) inclined for the first axis. A first end portion of the third body is installed in a second end portion(24) of the second body to be rotated around a third axis(VI) inclined for the second axis. The first and third axes are perpendicular to the second axis and aligned for each other on at least one position. |
