Extension jig for annular elastic part and method for manufacturing wire harness with annular elastic part

摘要

PROBLEM TO BE SOLVED: To provide an annular elastic part capable of being easily attached onto branch part of wire harness etc.SOLUTION: An extension jig 20 extends annular elastic part upon the annular elastic part (for example, elastic connector cover) is attached onto a wire harness 12. The extension jig 20 comprises 3 or more extension members 22 arranged on predetermined axis X. Each of the 3 or more extension members 22 comprises extension part 25 extending to one direction side of the predetermined axis X; a base part 24 movably supported on its base side part along with radiation direction centered on the predetermined axis X, a middle connecting part 28 extending from tip end part of the extension part 25 to predetermined axis X; and an insertion part 29 extending from the tip end part of middle connecting part 26 to the other side in the predetermined axis X direction.SELECTED DRAWING: Figure 2
