1. An articulated robot, comprising:
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,
wherein a cable body is wired from the base to the arm through an inside of the shaft, and
wherein the articulated robot further comprises 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.
