JP 2013-42658 A

  According to the above configuration, for example, when the slider moves back and forth, the wire harness connected to the slider also moves in the rail along with the slider. As described above, since a plurality of electric wires are housed in the corrugated tube in the wire harness, when the wire harness moves in the rail, the inner surface of the rail and the outer surface of the corrugated tube come into sliding contact. Then, there is a concern that the corrugated tube is scraped and damaged. The present invention has been completed based on the above circumstances.

  The wire harness routing device according to the present invention includes a metal rail, a slider that is slidably disposed on the rail, and a plurality of electric wires that are externally covered with a resin outer body and connected to the slider. A wire harness, and the wire harness is disposed inside the rail, and a resin protective member is interposed between the rail and the wire harness.

  According to the present invention, even when the wire harness connected to the slider moves in the rail by sliding the slider, the resin-made exterior body is in sliding contact with the resin-made protective member. Thereby, it can suppress that an exterior body is damaged compared with the case where an exterior body is slidably contacted with metal rails.

  As embodiments of the present invention, the following embodiments are preferable.

  The rail has an upper wall, and a through groove through which at least a part of the slider is inserted is formed in the upper wall, and the protection member is arranged at a position different from a region facing the through groove. It is preferable that

  According to said structure, since the protection member is distribute | arranged in the position different from the area | region which opposes a through groove, it is suppressed that the foreign material which fell in the rail from the through groove penetrate | invades in a protection member. Thereby, since it can suppress that the wire harness arrange | positioned in the protection member contacts a foreign material, a wire harness can be moved smoothly in a protection member.

  The rail has an upper wall, and a through groove into which at least a part of the slider is inserted is formed in the upper wall, and the protection member has an introduction groove into which the wire harness is introduced. The introduction groove is preferably opened at a position not facing the through groove.

  According to the above configuration, since the introduction groove of the protective member is opened at a position not facing the through groove, foreign matter falling from the through groove formed on the upper wall of the rail enters the introduction groove. This can be suppressed.

  The protective member preferably has an introduction groove into which the wire harness is introduced, and the introduction groove is orthogonal to the through groove and opens in a direction in which the through groove is located.

  According to the above configuration, since the introduction groove of the protection member is orthogonal to the through groove and opens in the direction in which the through groove is located, foreign matter that falls from the through groove formed in the upper wall of the rail is introduced. Intrusion into the groove can be suppressed.

  In addition, the wire harness connected to the slider disposed in the through groove provided on the upper wall of the rail is routed from the introduction groove that is orthogonal to the through groove and opens in the direction in which the through groove is located to the inside of the protective member. do it. That is, the wire harness can be routed toward the introduction groove at the height position where the introduction groove opens after the rail is suspended downward from the through groove on the upper wall. Can be prevented from increasing in size.

  ADVANTAGE OF THE INVENTION According to this invention, it can suppress that the exterior body of a wire harness is damaged.
