Provided is a structure of a joint portion which suppresses deterioration or damage of a seal member arranged inside the joint portion. The joint portion rotates a first structure portion and a second structure portion relatively to each other. The structure of the joint portion comprises: an oil seal which is arranged in a gap portion; and a labyrinth member which is arranged on outer surfaces of the first structure portion and the second structure portion. The labyrinth member comprises a passage which communicates with the gap portion. The labyrinth member is formed so as to be attachable to the outer surface of the first structure portion and the outer surface of the second structure portion. Further, the labyrinth member is formed so as to be detachable from the first structure portion and the second structure portion.

Structure of drive portion for relatively rotating plurality of structure portions and robot comprising joint portion

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.
