<p>PROBLEM TO BE SOLVED: To provide a multi-joint robot which can prevent and suppress dust generation in a storage space by suppressing the abrasion of wiring piping arranged spirally in the storage space.SOLUTION: A multi-joint robot comprises a wiring piping storage part 8 the inner peripheral surface 81 of which is the outer peripheral surface of a first rotation shaft 53 around the axis center and the outer peripheral surface 82 of which is a face of the first rotation shaft 53 opposite the inner peripheral surface 81 in the radial direction of the first rotation shaft 53. Out of the bottom face 83 of the wiring piping storage part 8, an inner wheel part 84 continuous to the inner peripheral surface 81 and an outer wheel part 85 continuous to the outer peripheral surface 82 of the wiring piping storage part 8 are set as taper faces higher than other parts and constituted so that the whole or a part of the wound part of the innermost periphery of a wiring piping CT (5) drawn from a draw-in hole 48b into a wiring piping storage space 8S to be arranged spirally may come into contact with the inner wheel part 84, and a part in a vicinity of a part drawn out of a draw-out hole 53b of at least the wiring piping CT (5) and arranged in the wiring piping storage space 8S may come into contact with the outer wheel part 85.</p> |
