FIG. 4 is a sectional view taken along the line ii, showing the outer periphery of the wire harness a formed by bundling a large number of covered electric wires a 1 .
It is constructed by using a curable resin and molding and curing it into a desired shape according to the wiring path to form the outer package b.

撓性及び自己復帰性が得られないため外装に負荷がかか
り、亀裂を生じさせるなどの問題があった。The molded wire harness formed in this way can always be molded into a constant shape according to the shape of the car using a molding die, so like conventional wire harnesses, the wires are manually wrapped with adhesive cheap Compared to the case of fixing, there is no variation in shape, it is possible to rationalize the wiring work, and to prevent vibration due to interference and contact with various parts of the vehicle, protect the wire harness itself and make abnormal noise Although it has excellent characteristics such as preventing the occurrence of heat generation, on the other hand, the exterior b has a molding resin as shown in FIG.
Since b 1 is cured while being filled in the gaps between the electric wires a 1, there is a drawback that it is almost inflexible. For this reason, when the wire harness that is routed from the fixed part of the automobile to the movable parts such as the bonnet, trunk, and various doors is covered with a fixed shape, it is flexible and self-restoring for these movements. Since the property is not obtained, there is a problem that a load is applied to the exterior and cracks occur.

供することを目的とする。(Problems to be solved by the invention) The present invention has been made by paying attention to the drawbacks of the conventional molded wire harness, and has the above-mentioned characteristics of the molded wire harness as they are, and has a flexible exterior. An object of the present invention is to provide a flexible molded wire harness that is provided with self-recovery.
（問題点を解決するための手段） 以下に本考案を実施例を示す添付の図面に基づいて詳細

形成させることにより構成される。Referring to the drawings, the flexible molded wire harness of the present invention is configured such that the wire harness 1 is inserted into a flexible tube 2 without being fixed, and an insulating resin material is molded on the outer periphery of the tube 2 into a desired wiring shape. It is configured by curing to form the exterior 3.

外装３の位置ずれを防止することができる。In this configuration, as the material of the tube 2 through which the wire harness 1 is inserted, a resin such as soft vinyl chloride or polyethylene having excellent flexibility and low self-recovery property is preferably used. Further, the tube 2 can be provided with slits in the lengthwise direction partially or over the entire length to facilitate the mounting of the wire harness 1 into the tube 2. When the tube 2 is provided with a slit, it is desirable to apply a tape winding to a key portion to prevent the tube 2 from losing its shape.
Further, it is desirable that the tape winding is performed to fix both ends of the tube 2 to the wire harness 1 regardless of whether or not the slit is formed in the tube 2, and thus the degree of freedom of the wire harness 1 in the tube 2 is increased. It is possible to prevent the positional displacement of the tube 2 and the external sheath 3 with respect to the wire harness 1 while holding

A method as disclosed in Japanese Patent No. 1191, that is, using a mold including a receiving mold provided with a molding groove corresponding to a desired shape to be applied to the exterior 3 and a pressing mold corresponding to the receiving mold, It can be easily carried out by molding and curing a curable resin material by a conventional method. in this case,
If polyurethane or polystyrene is used as the resin material and foam molding is performed, the outer casing 3 can be formed to be lightweight. In addition, a protective film may be provided on the outer circumference of the outer package 3 to provide surface protection for the outer package 3 and provide stools for different colors.
