<p>A multiple driving device (30) capable of causing one output element (10, 40) of an industrial robot to move rectilinearly in one axial direction and of causing the output element (10, 40) to independently swing about the same axis is provided with a driving motor (M2) for giving swinging motion to the element (10, 40) rectilinearly movable in accordance with the drive of a motor (M1) for driving in the rectilinear motion at a fixed position as viewed from the output element (10, 40), and with a rotary bearing (18, 46) between means (12, 14; 42, 44) for transmitting rectilinear movement to the output element (10, 40) and means (18, 20; 48, 50) for transmitting swinging motion to the same, thereby obviating mutual interference between the both means.</p> |
