PURPOSE:To provide the revolute joint section driving structure for an industrial robot, which can materialize arm operations of high frequency. CONSTITUTION:In the revolute joint section driving structure for an industrial robot in which the box shaped end section 11 of a first arm 1 and the box shaped end section 21 of a second arm 2 are connected to each other in such a way that they can be rotated via a bearing 23, the output section of a speed reducer 5 is connected to the rotating shaft of a drive motor 4 rotatably driving the second arm, and the drive motor 4 is built in the end section 21 of second arm 2, a bracket 41 at the half load side, which is fixed to the fixed section 40 of the drive motor 4, is fixed to the end section 21 of the second arm 2. Furthermore, the fixed section 51 of the speed reducer 5 is fixed to the fixed section 40 of the drive motor 4, and a speed reducing mechanism section 53 acting as the output section of the speed reducer 5 is fixed to the end section 21 of the first arm 1. |
