Abstract
An articulated robot including a base, an arm supported so as to be rotatable about a predetermined axis with respect to the base and rotatable within a rotational angle range smaller than ±180°, and a hollow shaft that is disposed outside the rotational angle range and stands upward from the base to be parallel to the axis. A cable body is wired from the base to the arm through an inside of the shaft. The articulated robot includes a stopper embedded in a side surface of the shaft, the stopper against which a side surface of the arm rotated beyond the rotational angle range abuts.
