Abstract
An industrial robot may include a main body section, a first arm, a second arm, a third arm, a first speed reducer which connects the main body section and the first arm, a second speed reducer which connects the first arm and the second arm, and a connecting mechanism which connects the input shaft of the first speed reducer and the input shaft of the second speed reducer, and a second drive motor which drives the third arm. The speed reduction ratio of the first and second speed reducer are set such that the movement loci of a third articulation section which connects the second and third arm are rectilinear. The connecting mechanism connects the input shafts at a predetermined speed ratio. The second drive motor is mounted on the second arm closer to the tip than where a third articulation section is located.
