The cover 30 is fixed to the exterior member 20 with screws.

  Locking recesses 37 are formed on the inner side surfaces of the side walls 32 of the bracket cover 30. The locking recess 37 is disposed in the vicinity of the base end 33 of the bracket cover 30 so that the locking projection 27 of the exterior member 20 is positioned in the locking recess 37 when the bracket cover 30 is attached to the exterior member 20. ing. Further, the proximal end side 37A of the locking recess 37 is an opening, and the locking projection 27 of the exterior member 20 can enter the locking recess 37 from the opening of the end 37A. Yes.

  The upper end edge of the locking recess 37 is a curved portion 38 that is concavely curved into an arc shape. The curved portion 38 of the locking concave portion 37 has a shape that is exactly aligned with the curved portion 28 of the locking convex portion 27, and is from the base end 33 side (the mounting side of the bracket body 5 to the installation portion 4). As it leaves, it is concavely curved so as to incline toward the lower side (the side opposite to the exterior member 20). Thus, when the locking projection 27 of the exterior member 20 is engaged in the locking recess 37 of the bracket cover 30, the curved portion 38 of the locking recess 37 faces the curved portion 28 of the locking projection 27. Are arranged adjacent to each other.

  Next, with reference to FIG.7 and FIG.8, the attachment or detachment of the bracket cover 30 with respect to the exterior member 20 (bracket main body 5) is demonstrated. In these figures, the bracket member 10 is not shown for the sake of simplicity.

  FIG. 7 shows a state where the bracket cover 30 is attached to the exterior member 20 (the bracket body 5). As shown in the figure, in this mounted state, the bracket cover 30 is mounted from the lower side with respect to the exterior member 20 that covers the upper portion of the bracket member 10, and the locking projections of the locking pieces 26 of the exterior member 20. The portion 27 is engaged with the locking recess 37 of the bracket cover 30. Since this engagement is made in a direction (lateral direction) substantially orthogonal to the direction (vertical direction) in which the bracket cover 30 is superimposed on the exterior member 20, the bracket cover 30 (particularly the base end portion 33). Even if the side) is pulled downward, the curved portion 38 of the locking recess 37 abuts and locks against the curved portion 28 of the locking projection 27 of the locking piece 26, so that the bracket cover 30 is secured to the exterior member 20. It is designed not to come off.

  As described above, in a state where the engagement convex portion 27 and the engagement concave portion 37 are engaged with each other, in the screwing convex portion 25 of the exterior member 20 and the screwing concave portion 35 of the bracket cover 30, The bracket cover 30 is completely fixed to the exterior member 20 by being stopped. Here, when the portion on the distal end edge 34 side of the bracket cover 30 is fixed to the bracket body 5 with the screw 19, the portion on the proximal end edge 33 side of the bracket cover 30 is pulled away from the bracket body 5. In addition, if the engagement between the locking projection 27 and the locking recess 37 is easily released as in the conventional bracket cover, the portion of the bracket cover 30 closer to the base edge 33 than the screw 19 is forcibly opened. The bracket cover 30 may be cracked or broken. In this embodiment, however, the engagement between the locking projection 27 and the locking recess 37 is maintained, and thus the bracket cover 30 is forced. It will not open and break.

  In FIG. 8, the state in the middle of removing the bracket cover 30 from the exterior member 20 (bracket main body 5) is shown. To remove the bracket cover 30 from the exterior member 30, the screw 19 is removed from the screwing convex portion 25, and the bracket cover 30 is opened with the lower edge portion 33 </ b> A of the base edge 33 as a fulcrum ( It can be rotated in the clockwise direction of FIG.

  In this way, by engaging the bracket cover 30 with the lower edge portion 33A of the base end edge 33 as a fulcrum, the engagement of the engagement protrusion 27 and the engagement recess 37 is smoothly released. . That is, the curved portion 27 of the locking convex portion 27 and the curved portion 28 of the locking concave portion 37 are formed in an arc shape along a virtual circumference centering on the lower edge portion 33 </ b> A of the base end edge 33. When the bracket cover 30 is rotated clockwise with respect to the exterior member 20, the curved portion 38 of the locking recess 37 slides on the curved portion 28 of the locking projection 27, and finally the locking recess. Thus, the curved portion 38 of the latch 37 is disengaged from the curved portion 28 of the latching convex portion 27 (in other words, the latching convex portion 27 comes out of the latching concave portion 37). As a result, the engagement between the locking projection 27 and the locking recess 37 is released, so that the bracket cover 30 can be removed from the exterior member 20. Therefore, the engagement of the locking projection 27 and the locking recess 37 can be released very easily and smoothly only by rotating the bracket cover 30 with respect to the exterior member 20. Work efficiency can be improved.

  On the other hand, in order to attach the bracket cover 30 to the exterior member 20, the lower edge portion 33A of the base end edge 33 is used as a fulcrum and the direction opposite to the removal of the bracket cover 30 described above (counterclockwise direction in FIG. 8). And the locking projection 27 of the exterior member 20 is inserted into the locking recess 37 from the opening of the end portion 37A of the side wall 32, and the locking projection 27 and the locking recess 37 are engaged. Accordingly, the bracket cover 30 can be attached to the exterior member 20. Alternatively, the bracket cover 30 is covered from the front side of the bracket member 10, and the locking convex portion 27 of the exterior member 20 is inserted into the locking concave portion 37 from the opening of the end portion 37 </ b> A of the side wall 32. It is also possible to attach the bracket cover 30 to the exterior member 20 by engaging the engagement recesses 27 with the locking recesses 37. Alternatively, when the bracket cover 30 is covered from the lower side of the bracket member 10 along the installed portion 4, the sliding contact portion 39 (see FIG. 6) on the inner surface of the side wall 32 presses the locking convex portion 27 of the exterior member 20. Then, the locking piece 26 is bent, but when the sliding contact portion 39 gets over the locking projection 27 of the locking piece 26, the locking piece 26 is elastically deformed and the locking projection 27 becomes the locking recess 37. Engage. In this manner, the bracket cover 30 can be attached to the exterior member 20.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, In the range described in the claim, an appropriate change is possible. For example, in the above embodiment, the locking projection 27 is provided on the exterior member 20 (bracket body 5) side and the locking recess 37 is provided on the bracket cover 30 side, but the present invention is in such a form. However, the present invention is not limited to this, and a locking recess may be provided on the exterior member 20 (bracket body 5) side, and a locking protrusion may be provided on the bracket cover 30 side.

  Moreover, in the said embodiment, although the latching piece 26 provided with the latching means was provided in the exterior member 20, this invention is not restricted to such a form, A latching piece is on the bracket cover 30 side. It is also possible to provide a locking recess on the exterior member 20 (bracket body 5) side.

  Moreover, in the said embodiment, although the bracket member 10 and the exterior member 20 which were formed separately were combined and it was set as the bracket main body 5, this invention is not limited to such a form, The bracket member 10 and an exterior member The bracket main body 20 may be integrally formed, and a locking means may be provided between the bracket main body and the bracket cover 30 so that the bracket cover 30 is attached to and detached from the bracket main body.
