A window regulator (not shown) that allows the window glass 13 to move forward and backward A is provided in the space 8. The window regulator is an electric type and includes an electric motor 16. An inner panel 6 of the door body 2 is covered from the outside (vehicle compartment side), and a door trim (not shown) supported by the inner panel 6 is provided.

  A wire harness 18 for connecting the electric motor 16 to a control device provided on the vehicle body side and a power source is provided. A part of the wire harness 18 is installed in the space 8 in the vicinity of the opening 9. A resin wire harness clamp 19 for attaching a part of the wire harness 18 to the opening edge of the opening 9 is provided.

  A circular locking hole 23 in which an axis 22 is orthogonal to the inner panel 6 is formed at the opening edge of the opening 9 of the inner panel 6 that is the end edge 21 of the stationary member 20. The clamp 19 is fitted into the locking hole 23 so as to be detachable and can be locked to the end edge portion 21, and the clamp 19 extends integrally from the locked portion 24. The extension portion 25 is provided with an attachment arm 27 that allows a part of the wire harness 18 to be attached by a fixture 26. The extension portion 25 corresponds to the extension end portion of the mounting arm 27.

  The inner area 29 of the stationary side member 20 (inner panel 6) corresponds to the space 8. The outer region 30 of the stationary side member 20 corresponds to the outside (vehicle compartment side) of the inner panel 6. A base portion 32 that is an end portion of the mounting arm 27 on the locked portion 24 side is located in the outer region 30. The mounting arm 27 is formed so as to bypass the end edge portion 21 of the stationary side member 20 from the base portion 32 side so that the extending portion 25 is positioned in the inner region 29. The mounting arm 27 is formed in a U shape that is externally fitted to the end edge portion 21 when viewed in the direction along the end edge portion 21 of the stationary side member 20 (FIG. 1).

  The fixture 26 is a band using a surface tape, but may be an adhesive or a clip.

  As shown in FIG. 1, the locked portion 24 can be locked to the locking hole 23 from the outer region 30 side with the wire harness 18 attached to the extending portion 25 of the mounting arm 27. It is said that. In the state where the locked portion 24 is locked in the locking hole 23 and the wire harness 18 is attached to the end edge portion 21 of the stationary side member 20 (solid line in FIG. 1), the locking hole 23 In this radial direction, the end surface 21a of the end edge 21 and the partial outer surface 27a of the mounting arm 27 facing the end surface 21a are brought close to each other.

  In FIG. 1, an assembly operation for assembling the wire harness 18 to the stationary member 20 using the clamp 19 will be described. First, in the outer region 30, the wire harness 18 is attached to the extending portion 25 of the attachment arm 27 by the attachment tool 26. Next, in the outer region 30, the locked portion 24 is positioned with respect to the locking hole 23 by fitting the distal end portion of the locked portion 24 into the locking hole 23 (in FIG. 1, Dash-dot line).

  Next, as the work in the outer region 30, the locked portion 24 is pushed to fit into the locking hole 23. Then, with the progress of the fitting, the mounting portion 24 is moved to the inner region 29 together with the wire harness 18 with the fitting portion of the locked portion 24 to the locking hole 23 being substantially centered. The arm 27 rotates B, and the extending portion 25 of the mounting arm 27 enters deeper toward a predetermined position in the inner area 29. When the locking of the locked portion 24 to the locking hole 23 is completed, the wire harness 18 is installed in the inner region 29 together with the extending portion 25 of the mounting arm 27. The assembly work of the wire harness 18 to the end edge portion 21 of the stationary side member 20 is completed.

  That is, in the assembling operation, the wire harness 18 is attached to the extending portion 25 of the mounting arm 27, the locked portion 24 is positioned with respect to the locking hole 23, and the locked hole 23 is locked. Each operation of locking the portion 24 is performed in the outer region 30 on the side where the worker is present. For this reason, each of the above operations can be made unnecessary for the conventional operation of inserting a hand into the narrow inner region 29 from the outer region 30 side, and can be performed while visually observing all of them. Therefore, the above assembling work can be performed very easily.

  In addition, as described above, in the state where the locked portion 24 is locked in the locking hole 23 (solid line in FIG. 1), the end surface 21a of the end edge portion 21 is in the radial direction of the locking hole 23. And a part of the outer surface 27a of the mounting arm 27 facing the end surface 21a are brought close to each other.

  For this reason, when the locked portion 24 locked in the locking hole 23 tries to freely rotate C around the axis 22 of the locking hole 23, a part of the outer surface 27 a of the mounting arm 27 is Immediately abutting against the end surface 21a of the end edge portion 21, the free rotation C of the locked portion 24 is prevented.

  Therefore, in the assembling operation, as long as the locked portion 24 is locked in the locking hole 23, the clamp 19 and the wire harness 18 attached to the clamp 19 are automatically in a predetermined position. Retained. Therefore, the assembling work can be further facilitated accordingly. And since the wire harness 18 and the clamp 19 are held in a predetermined position in this way, it is reliably prevented that these 18 and 19 interfere with the operation of the window regulator and the reciprocation A of the window glass 13. Is done.

  Here, the locking hole 23 is formed into an oval shape or an oval shape, and a cross section of the locked portion 24 to be locked in the elliptical shape or an oval shape is used to freely rotate the locked portion 24. It is conceivable to prevent motion C. However, this makes the configuration of the locking hole 23 and the locked portion 24 complicated, which is not preferable.

  Therefore, as described above, the end surface 21a of the end edge portion 21 of the stationary side member 20 and the partial outer surface 27a of the mounting arm 27 are brought close to each other, thereby preventing free rotation C of the locked portion 24. For this reason, the shape of the locking hole 23 may be a simple circular hole as described above.

  FIG. 4 shows another assembling operation. According to this assembling operation, after the wire harness 18 is attached to the extending portion 25 of the mounting arm 27, first, the mounting arm 27 is externally fitted to the end edge portion 21 of the stationary side member 20, and the locking is performed. The locked portion 24 is positioned on the axial center 22 of the hole 23 (arrow D in FIG. 4). Next, the locked portion 24 is brought close to the locking hole 23 along the axis 22 (arrow E in FIG. 4), and locked in the locking hole 23. Then, the above assembling work is completed.

  Although the above is based on the illustrated example, the stationary side member 20 may be a vehicle panel other than an automobile or an equipment panel in an industrial machine.

  FIG. 5 below shows the second embodiment. The second embodiment is common in many respects to the configuration and operational effects of the first embodiment. Therefore, regarding these common items, common reference numerals are attached to the drawings, and redundant description thereof is omitted, and different points are mainly described. In addition, the configuration of each part in these embodiments may be variously combined in light of the object and operational effects of the present invention.

  In order to describe the present invention in more detail, Example 2 will be described with reference to FIG.

  According to this, the mounting arm 27 of the clamp 19 is substantially V-shaped.

  For this reason, the clamp 19 can be made smaller than the clamp 19 of the first embodiment. Therefore, the clamp 19 can be applied when the volume of the inner region 29 is smaller.
