Claim 1:
2. A robot cable-assembly management structure for a robot including a base to be installed on an installation surface, a turning drum supported so as to be rotatable about a vertical first axis with respect to the base, and an arm supported so as to be swingable about a horizontal second axis with respect to the turning drum, the cable-assembly management structure wiring a cable assembly from the turning drum to the arm, the cable-assembly management structure comprising:
a first fixing member that fixes, to the turning drum, a first intermediate portion of the cable assembly extending beside the turning drum in a front-rear direction of the turning drum, at a position between the base and a base end of the arm; and
a second fixing member that fixes, to a side surface of the arm, a second intermediate portion of the cable assembly extending to a front side of the first fixing member, at a position closer to a distal end of the arm than the second axis, wherein
a movable portion of the cable assembly located between the first fixing member and the second fixing member is provided with slack to allow for movement of the arm, and the second fixing member is inclined toward a rear side of the arm with respect to the longitudinal-axis direction of the arm such that a portion of the second fixing member closer to a distal end of the arm is located closer to the rear side of the arm, so that the movable portion is located near the side surface of the arm when the arm swings to a rear swing end and the movable portion is bent in a direction away from the side surface of the arm as the arm swings toward a front swing end.
