PROBLEM TO BE SOLVED: To provide an articulated industrial robot arm which is simple in structure, and free in configuration. SOLUTION: First and second axial units (1, 2) of the robot arm are comprised of reduction gear-integrated motors (10, 20), respectively, which each have a reduction gear mechanism built therein in one body. According to the configuration of the robot arm, the second axial unit (2) has a static portion of the motor directly fixed to a reduction gear mechanism output shaft of the motor of the first axial unit (1). Alternatively the second axial unit is linked to the first axial unit (1) via a bracket (21). The bracket has the static portion or a reduction gear mechanism output shaft of the motor (20) of the second axial unit fixed to one side thereof, and has the other side thereof fixed to the reduction gear mechanism output shaft of the motor (10) of the first axial unit.
