Abstract
An industrial robot including a first arm which has a first arm portion, and a second arm portion supported by the first arm portion. The industrial robot also includes a second arm which has a third arm portion and a fourth arm portion supported by the third arm portion. The first arm and the second arm can be expanded/retracted independently. A turning center of the first arm portion and a turning center of the third arm portion are placed coaxially. The first arm and the second arm are constructed so as to be almost line-symmetric with respect to an imaginary line under the condition that the first arm and the second arm are retracted. The first arm portion, the third arm portion, the second arm portion, and the fourth arm portion are placed in this order in a vertical direction.
