Thus, the corrugated tube 13 accommodates the electric wires of the electric wire bundle 11 positioned between the vehicle body 3 and the slide door 4 and protects the electric wires of the electric wire bundle 11 (restricts damage).

  Further, as shown in FIG. 7, the end portion 13 a of the corrugated tube 13 has a positioning projection 24 inserted between the adjacent convex portions 30, that is, in the concave portions 31, so that the outer case 14 of the vehicle body side fixing member 12, that is, the vehicle body 3. It is positioned and fixed.

  The leaf spring 7 is made of metal, and as shown in FIG. 6, the planar shape is formed in a rectangular plate shape. The leaf spring 7 is elastically deformable and naturally generates an elastic restoring force when elastically deformed. The leaf spring 7 is provided with a hole 32 into which the above-described protrusion 25 can enter. The hole 32 is provided in one end portion 7 a of the leaf spring 7. As shown in FIG. 5, the leaf spring 7 has the other end portion 7b accommodated in the one end portion 13a of the corrugated tube 13 and fixed to the one end portion 13a, and the projection 25 enters the hole 32 and the one end portion 7a.

Guide to the above-mentioned auxiliary machine on the slide door 4 side. Thus, the door fixing part 6 protects the electric wires of the electric wire bundle 11 of the wire harness 5 described above. When the sliding door 4 slides relative to the vehicle body 3, the door fixing portion 6 is pulled around the axis center described above by pulling the rotating member 19 by the corrugated tube 13 of the wire harness 5. While rotating, the slider 18 slides along the rail 17.

  The door fixing portion 6 rotates the rotating member 19 and slides the slider 18 by opening and closing the slide door 4, thereby reducing the load accompanying opening and closing of the slide door 4 acting on the electric wire of the wire harness 5. When the slide door 4 is positioned at the closing position described above, the slider 18 is positioned near the vehicle body side fixing member 12, that is, the end of the rail 17 near the rear of the vehicle 2, and the rotating member 19 is moved from the slider 18 to the vehicle body. The side fixing member 12, that is, the vehicle 2 is positioned in the rearward direction. When the slide door 4 is positioned at the above-described open position, the slider 18 is positioned near the vehicle body side fixing member 12, that is, the end of the rail 17 near the front of the automobile 2, and the rotating member 19 is moved from the slider 18 to the vehicle body. The side fixing member 12, that is, the vehicle 2 is positioned in a forward direction.

  According to the present embodiment, since the leaf spring 7 is attached across the one end portion 13a of the corrugated tube 13 and the vehicle body side fixing member 12 of the vehicle body 3, the slide door 4 is particularly located between the closed position and the open position. When the corrugated tube 13 is bent, the corrugated tube 13 is kept as straight as possible when it is positioned at an intermediate position (shown by a solid line in FIG. 1 and also called a half-open state).

  Thus, when the slide door 4 slides and the corrugated tube 13 bends, the corrugated tube 13 is kept as straight as possible. Therefore, the slide door 4 is rotated when moved from the closed position to the open position. The member 19 can be prevented from rotating later than the predetermined timing, and the rotating member 19 can be prevented from rotating earlier than the predetermined timing when the slide door 4 is moved from the open position to the closing position. .

  For this reason, when the slide door 4 slides, as shown by a two-dot chain line X in FIG. 1, it is possible to prevent the central portion of the corrugated tube 13 from bending so as to swell outside the vehicle body 3. Therefore, the corrugated tube 13 can be prevented from rubbing against the slide door 4 when the slide door 4 is slid.

  Therefore, it is possible to prevent the corrugated tube 13 from rubbing against the slide door 4, to generate abnormal noise and to reduce the durability, and to prevent the wire harness 5 from being unexpectedly damaged.

  Further, when the slide door 4 is slid and the corrugated tube 13 is bent, the corrugated tube 13 is maintained as straight as possible, so that one end portion 13a of the corrugated tube 13 is hardly bent and the central portion 13c is the main portion. Turn to.

  For this reason, when sliding the slide door 4, it can prevent that the curve of the corrugated tube 13 swells to the outer periphery of this curve. For this reason, the amount of the corrugated tube 13 entering the vehicle body 8 and the degree of intrusion can be suppressed. Therefore, since the amount of the wire harness 5 entering the vehicle body 8 can be suppressed, the wire harness 5 can be prevented from interfering with articles in the vehicle body 8 to generate abnormal noise and reduce durability. This can prevent the wire harness 5 from being unexpectedly damaged.

  Further, since the leaf spring 7 is only attached to the one end portion 13a of the corrugated tube 13, the wire of the wire harness 5, that is, the wire bundle 11, is protected while suppressing the amount of the wire harness 5 entering the vehicle body 8 side. Therefore, it is not necessary to provide an article other than the corrugated tube 13 and the leaf spring 7. Therefore, an increase in the number of parts can be prevented, an increase in the number of man-hours required for assembly can be prevented, and an increase in cost can be prevented. Moreover, since the corrugated tube 13 integrally molded in a cylindrical shape is used, the strength of the corrugated tube 13 itself against impact can be improved, and the corrugated tube 13, that is, the wire harness 5 can be prevented from being unexpectedly damaged.

Thus, since the protrusion 25 penetrates into the hole 32 and the leaf spring 7 can be fixed to the vehicle body 3, the leaf spring 7 can be easily attached to the vehicle body 3, and the power feeding device 1 can be easily assembled. .

  Further, since the protrusion 25 enters the hole 32 and positions the leaf spring 7 in the vehicle body 3, it is possible to prevent the leaf spring 7 from being displaced with respect to the vehicle body 3. Therefore, the leaf spring 7 reliably generates the above-described elastic restoring force, and the amount of intrusion into the vehicle body 8 when the corrugated tube 13 is bent can be reliably suppressed.

  Further, the corrugated tube 13 is formed in a bellows shape, and a positioning projection 24 that enters the concave portion 31 of the corrugated tube 13 is provided on the outer case 14 of the vehicle body side fixing member 12 of the vehicle body 3. In contrast, the corrugated tube 13, that is, the wire harness 5 can be prevented from being displaced. Further, since a plurality of positioning protrusions 24 are provided, the corrugated tube 13 can be fixed to the vehicle body 3 without being displaced from the vehicle body 3.

  In the present invention, as shown in FIG. 8, the other end 7b of the leaf spring 7 may be covered with a synthetic resin 33 such as elastically deformable rubber. In this case, it is possible to prevent the leaf spring 7 from coming into direct contact with the corrugated tube 13 and damaging the corrugated tube 13.

  In the embodiment described above, the protrusion 25 is provided on the inner lid 15 of the vehicle body side fixing member 12 of the vehicle body 3, and the hole 32 is provided in the leaf spring 7.
