It can be moved to a routing position on the table and a retracted position.

  Therefore, when performing various operations on the harness in the post-process, the product jig on the jig support base is moved to the wiring position, so that a series of manufacturing processes for manufacturing the wire harness can be performed in one arrangement. It becomes possible to carry out on the rope. Therefore, compared to the case where the post-process work is performed on another routing table, it does not take time to transfer the harness to another routing table.
