A turning portion structure of an industrial robot enabling the easy assembling of the industrial robot and a reduction in cost for manufacturing the industrial robot. An idle gear (70) transmitting the rotation of the output gear (56) of a drive motor (54) to a cylindrical gear (61) is rotatably supported on a specific crankpin (40a) at its input side end part. Accordingly, the idle gear (70) may be merely supported on the crankpin (40a), and the axial length of the cylindrical gear (61) meshed with both the idle gear (70) and an input gear (60) is sufficient if it is slightly longer than the side end-to-side end distance of these both gears (70) and (60) separated from each other. |
