  In such a resin component mounting structure, when a wire harness (hereinafter referred to as a harness) is routed on the back side of the bracket, the harness and the screw are not damaged at the tip of the screw. A sufficient clearance is set between the tip of the wire and the route of the harness is regulated by using a harness clip or a harness protector.

  However, when an electronic unit or the like is mounted in the vicinity of the bracket, an extra length portion such as a work extra length portion having flexibility is required for the harness. The route regulation means cannot be applied.

  Therefore, it is necessary to take measures to prevent the extra length of the harness from touching the tip of the screw by providing a flange or cut-and-raised part on the bracket side. As the shape becomes complicated and it is inevitable that the harness will come into contact with the edge of the flange, cut-and-raised shape, etc., an exterior material such as a corrugated tube should also be attached to the harness side to prevent damage. Etc. are required.

  For this reason, normally, the design is such that the screw fixing portion is not set as much as possible in the vicinity of the extra length portion of the harness, which is a great design restriction.

  In order to solve the above-mentioned problem, in the invention described in claim 1, the bracket and the resin component are screwed and fixed via a screw fixing portion, and the screw fixing portion includes a locate hole formed in the bracket and In the resin part mounting structure having a screw hole and a locate pin and a screw hole formed in the resin part corresponding to the screw hole, a screw cover that has a resin hinge portion and can be bent and stretched is integrally provided on the locate pin. When the screw cover is inserted into the locating hole, the screw cover can be bent in a double-folded state, and after inserting into the locating hole, the screw tip can be returned to an initial bent state that can be protected. It is characterized by being configured to extend substantially linearly when detached.

  In the invention described in claim 2, the harness is routed in the immediate vicinity of the screw fixing portion in the bracket, and the peripheral portion of the screw fixing portion in the bracket can accommodate the flexible extra length portion of the harness. It is characterized by being an extra harness extra length accommodating part.

  According to the invention of claim 1, the locating pin is integrally provided with a screw cover having a resin hinge portion and capable of bending and stretching, and the screw cover can be bent in a double-folded state when inserted into the locating hole, In addition, after insertion into the locating hole, it is possible to return to the initial bent state that can protect the tip of the screw, and furthermore, when it is detached from the locating hole, it can be extended almost linearly, so the shape of the locating pin etc. With a slight change, it is possible to cover the tip of the screw and to separate the tip of the screw from the peripheral member easily and reliably, thereby protecting the peripheral member from the tip of the screw.

  According to the invention of claim 2, the harness is routed in the immediate vicinity of the screw fixing portion in the bracket, and the peripheral portion of the screw fixing portion in the bracket can accommodate the flexible extra length portion of the harness. Even if it is a case where sufficient clearance etc. cannot be secured due to the harness extra length accommodating part, the screw fixing part can be freely set to the nearest part while keeping the extra length part of the harness Can be eliminated, and design restrictions can be eliminated.

  Hereinafter, embodiments embodying the present invention will be described together with illustrated examples.

  1 to 4 show an embodiment of the present invention.

  First, the configuration will be described. Various types of resin parts 1 are attached to a vehicle such as an automobile inside or outside the vehicle. Such a resin component 1 is attached using a metal bracket 3 or the like provided on the vehicle body 2 side.

  For example, FIG. 1 shows an instrument panel 4 as a resin component 1 disposed in the front part of a vehicle interior. The instrument panel 4 is attached to a metal steering support member 5 as a strength component of the vehicle body 2 that connects the left and right vehicle body panels.

  That is, the steering support member 5 extends substantially in the vehicle width direction, and side brackets 6 are provided at both ends of the steering support member 5 for connecting to the left and right vehicle body panels. And the instrument panel 4 is attached using this side bracket 6 (bracket 3).

  Therefore, as shown in FIG. 2, a screw fixing portion 11 is provided between the bracket 3 and the resin component 1. The screw fixing portion 11 has a locate hole 12 and a screw hole 13 formed in the bracket 3, and a locate pin 14 and a screw hole 15 formed in the resin component 1 corresponding thereto. Then, the locating pin 14 is inserted into the locating hole 12 and the screw holes 13 and 15 are aligned and overlapped, and the screw 16 is screwed between the screw holes 13 and 15 from the resin component 1 side. Thus, the resin component 1 is fixed to the bracket 3 with screws.

  And in the thing of this Example with respect to the above basic structures, the screw cover 22 which has the resin hinge part 21 and can bend-extend is provided in the locate pin 14 integrally. The resin hinge portion 21 can be inserted into and removed from the locate hole 12 together with the locate pin 14. For this purpose, the screw cover 22 has a band shape slightly narrower than the locating hole 12, and the resin hinge portion 21 is set at an intermediate portion thereof. The rear end portion of the screw cover 22 is set so as to face the insertion direction of the locate pin 14 with respect to the locate hole 12. The screw cover 22 may be attached to the resin hinge portion 21 as a separate configuration from the resin hinge portion 21 or may be configured as a part of the resin hinge portion 21. In this case, the locate hole 12 is a square hole so that the width dimension of the screw cover 22 can be secured.

  As shown in FIGS. 3B and 3C, the screw cover 22 is configured to be bent in a two-fold state with the resin hinge portion 21 as the center when inserted into the locating hole 12. That is, the front end portion of the screw cover 22 is configured to bend along the locate pin 14 and the rear end portion.

  In addition, the screw cover 22 is configured to be able to return to an initial bent state capable of protecting the tip of the screw 16 after being inserted into the locate hole 12. That is, the angle of the resin hinge portion 21 in the initial bent state is an angle at which the portion on the tip side of the screw cover 22 can cover the screw hole 13 of the bracket 3 from the back surface side. Moreover, let the length of the part of the front end side of the screw cover 22 at this time be the length which can cover the screw hole 13 of the bracket 3 from the back surface side. In addition, the angle of the resin hinge part 21 at the time of an initial bending state is made into an acute angle so that it may become an insertion guide shape to the locating hole 12. FIG.

  Further, as shown in FIG. 4C, the screw cover 22 is configured to extend substantially linearly when it is detached from the locate hole 12.

  And it sets so that the harness 25 may be routed in the bracket 3 in the immediate vicinity of the screw fixing | fixed part 11. FIG.

  For example, in the case of FIG. 1, a main harness 28 is routed along the steering support member 5, and the main harness 28 includes an electronic unit 29 such as various connectors. Such an electronic unit 29 is also attached to the side bracket 6. In order to attach the electronic unit 29, the main harness 28 needs the extra length portion 26 as appropriate.

  Therefore, according to this, as shown in FIG. 2, the peripheral portion of the screw fixing portion 11 in the bracket 3 can be utilized as a harness surplus length accommodating portion 27 that can accommodate the flexible surplus length portion 26 of the harness 25. Configure. In this case, the harness surplus length accommodating portion 27 is a recess or the like that the surplus length portion 26 in the free state can follow.

  Next, the operation of this embodiment will be described.

  In assembling the front part of the passenger compartment in the vehicle, first, as shown in FIG. 1, the steering support member 5 is installed. A main harness 28 is routed to the steering support member 5, and electronic units 29 such as connectors of the main harness 28 are attached to the side bracket 6 of the steering support member 5. At this time, in the vicinity of the electronic unit 29, the extra length portion 26 for attaching the electronic unit 29 is left in a bent state. The extra length portion 26 is in a free state because it cannot apply a route restricting means such as a harness clip or a harness protector. The instrument panel 4 is attached to such a steering support member 5.

  Here, the instrument panel 4 is the resin component 1, the side bracket 6 is the metal bracket 3, and the main harness 28 is the harness 25.

  And when attaching the resin component 1 with respect to the bracket 3, as shown in order to Fig.3 (a)-(f), the locating pin 14 is inserted in the locating hole 12 which comprises the screw fixing | fixed part 11, and the screw hole 13, The resin part 1 is screwed and fixed to the bracket 3 by screwing screws 16 between the screw holes 13 and 15 from the resin part 1 side in a state where the 15 are aligned and overlapped.

  When the locating pin 14 is inserted into the locating hole 12, as shown in FIGS. 3A to 3C, the tip side portion of the screw cover 22 is bent in a double-folded state around the resin hinge portion 21. Enter the locate hole 12. At this time, since the angle of the resin hinge portion 21 in the initial bent state is an acute angle, this shape serves as an insertion guide to the locate hole 12, and the locate can be performed without performing the operation of bending the resin hinge portion 21 by hand. Since the resin hinge portion 21 naturally bends in when passing through the hole 12, it is convenient.

  After the insertion into the locate hole 12, the screw cover 22 is returned to the initial bent state by the elasticity of the resin hinge portion 21 as shown in FIG. Then, as shown in FIGS. 3E to 3F, by screwing the screw 16 between the screw holes 13 and 15, the tip of the screw cover 22 is protected at the tip side of the screw cover 22, and the screw 16 is screwed. It is possible to prevent the tip of 16 from hitting the extra length portion 26 of the harness 25.

  On the contrary, when removing the resin component 1 from the bracket 3, the screw 16 is removed from between the screw holes 13 and 15, and the resin component 1 is pulled away from the bracket 3.

  When the locating pin 14 is detached from the locating hole 12, as shown in FIGS. 4 (a) to 4 (c), the screw cover 22 has the resin hinge portion 21 extended by the portion on the tip side coming into contact with the locating hole 12. It will be extended almost linearly. Thereby, even if there is the screw cover 22, it becomes possible to remove the resin component 1 without hindrance.

  As described above, according to this embodiment, the locating pin 14 is integrally provided with the screw cover 22 having the resin hinge portion 21 and capable of bending and extending, and the screw cover 22 is folded in two when being inserted into the locating hole 12. Can be bent, and after being inserted into the locating hole 12, the tip of the screw 16 can be restored to an initial bent state that can be protected, and can be extended substantially linearly when detached from the locating hole 12. As a result, the shape of the locate pin 14 and the like are slightly changed, and the tip of the screw 16 is covered and the tip of the screw 16 and the peripheral member are easily and reliably separated from each other. It becomes possible to protect.

  In addition, the harness 25 is routed near the screw fixing portion 11 in the bracket 3, and the harness surplus length in which the peripheral portion of the screw fixing portion 11 in the bracket 3 can accommodate the flexible extra length portion 26 of the harness 25. Even if it is a case where sufficient clearance or the like cannot be secured due to the use of the accommodating portion 27, the screw fixing portion 11 is freely set with respect to the nearest portion thereof along the surplus length portion 26 of the harness 25. It is possible to eliminate the design restrictions.
