  As shown in FIG. 5, the license plate bracket 23 has a frame portion 60 having a mounting surface 60 a to which the license plate is attached, and a bottom wall portion 61 rivet-bonded to the spacer 22, and an inner edge of the frame portion 60. And a recess 62 integrally connected thereto. The license plate bracket 23 has an illumination mounting portion 64 that is integrally connected to the upper center portion of the frame portion 60 as a portion to which the number lamp 63 that illuminates the license plate is mounted.

  The frame portion 60 has a pair of left and right support portions 65 that support the lower portion of the license plate and a pair of left and right insertion holes 66 through which bolts (not shown) for fastening the upper portion of the license plate to the frame portion 60 are inserted. It is formed in the position which sandwiches. The frame 60 is provided with a welding nut (not shown) to which a bolt that passes through the insertion hole 66 is fastened on the surface on the back side of the mounting surface 60a. The frame portion 60 is inclined with respect to the bottom wall portion 61 so that the portion positioned below is positioned on the rear side of the vehicle body so that the mounting surface 60a faces obliquely upward of the vehicle body.

  The bottom wall portion 61 of the recess 62 has a flat plate shape and is in surface contact with the mounting plate 48 of the spacer 22. The bottom wall portion 61 is formed with a pair of pilot holes 67 as a reference at the time of processing, and a plurality of rivet holes 68 so as to surround the pair of pilot holes 67.

  As shown in FIG. 6, the license plate bracket 23 described above is rivet-bonded to the spacer 22 fixed to the end cross member 12. First, the rivet holes 53 and 68 are aligned with each other with the bottom wall portion 61 of the license plate bracket 23 superimposed on the mounting plate 48 of the spacer 22. Then, the blind rivet 69 is inserted into the overlapping rivet holes 53 and 68 from the bottom wall 61 side, and the spacer 22 and the license plate bracket 23 are rivet-joined using a riveter or the like. As a result, the support 20 is installed on the end cross member 12. At this time, the fastening opening 51 of the spacer 22 is covered with the covering portion 70 of the license plate bracket 23.

The operation of the above-described license plate bracket mounting structure will be described with reference to FIG.
As shown by a two-dot chain line in FIG. 7, when the license plate bracket 23 is riveted to the rivet hole 17 of the end cross member 12, a part of the license plate 72 may be covered by the tail lamp 71. is there. In such a case, the license plate bracket 23 is fixed to the end cross member 12 via the setting plate 21 and the spacer 22, whereby the display position of the license plate 72 can be changed to a position that does not overlap the rear lamp 71.

  In the support 20, the setting plate 21 and the spacer 22 are fastened to the end cross member 12 by the first and second fastening members 26 and 27, and the license plate bracket 23 is riveted to the spacer 22. That is, since the welding work is not required when installing the support 20 on the end cross member 12, it is possible to prevent the work of moving the license plate 72 from becoming complicated.

  In the support 20, the fastening opening 51 of the mounting plate 48 is covered with the covering portion 70 of the license plate bracket 23. Therefore, when the license plate bracket 23 is riveted to the spacer 22, the access to the tool to the first nut 29 through the fastening opening 51 is obstructed by the covering portion 70. In addition, a surrounding portion 52 including an upper facing piece 43, a lower facing piece 44, a right facing piece 49, and a left facing piece 50 surrounds the first nut 29 from four directions. Therefore, access of the tool to the first nut 29 through between the base plate 42 and the mounting plate 48 is hindered. That is, since it is difficult to relax the first fastening member 26, the support tool 20 cannot be easily detached from the end cross member 12.

According to the mounting structure of the license plate bracket of the above embodiment, the following effects can be obtained.
(1) Since a welding operation is not required when the license plate 72 is moved, it is possible to prevent the license plate moving operation from being complicated. Further, the support 20 after the license plate 72 is attached cannot be easily detached from the end cross member 12.

  (2) The support 20 is fastened to the end cross member 12 by the first and second fastening members 26 and 27. The second fastening member 27 includes a second bolt 30 joined to the spacer 22 and a second nut 31 fastened to the second bolt 30 from the setting plate 21 side.

  Therefore, for the second fastening member 27, it is not necessary to form the fastening opening 51 like the first fastening member 26 in the spacer 22, and the size of the fastening opening 51 formed in the mounting plate 48 is reduced. it can. Thereby, the position where the license plate bracket 23 is attached to the attachment plate 48, that is, the degree of freedom of the display position of the license plate 72 is improved.

  (3) The surrounding portion 52 surrounds a portion of the second fastening member 27 as well as the first fastening member 26 located between the base plate 42 and the mounting plate 48. Therefore, for example, not only the first fastening member 26 but also the second fastening member 27 can be protected from scattered matter such as stepping stones.

  (4) The rivet hole 53 of the spacer 22 is located on the inner side of the surrounding portion 52 constituted by the upper facing piece 43, the lower facing piece 44, the right facing piece 49, and the left facing piece 50 in the mounting plate 48. It is formed in the part located in. That is, the engaging portion of the blind rivet 69 with respect to the spacer 22 is located inside the surrounding portion 52. For this reason, it becomes difficult to remove the license plate bracket 23 from the spacer 22 by breaking the engaging portion.

  (5) In the spacer 22, the mounting plate 48 of the mounting member 41 protrudes below the upper flange portion 48 a that protrudes above the upper facing piece 43 of the base member 40 and the lower facing piece 44 of the base member 40. And a lower flange 48b. Thereby, joining of the base member 40 and the attachment member 41 can be performed easily.

  (6) Since the first nut 29 is surrounded from the four sides by the surrounding portion 52, the access of the tool to the first nut 29 from all directions between the base plate 42 and the mounting plate 48 is likely to be hindered. Thereby, the freedom degree of the formation position of the 1st penetration hole 45 improves, and also the freedom degree regarding the display position of the license plate 72 also improves.

  (7) In the base plate 42 of the base member 40, the first insertion hole 45 is formed at a position closer to the center in the extending direction of the base member 40. Therefore, for example, even when a tool is accessed to the first nut 29 through the right opening 55, the operation range of the tool can be effectively limited.

  (8) Here, the end cross member 12 is made of a pressed steel plate. Therefore, for example, the display position of the license plate 72 can be changed by changing the position of the rivet hole 17 of the end cross member 12. However, if a press mold is newly manufactured to change the position of the rivet hole 17, a great cost is generated. It is also possible to form a new rivet hole in the end cross member 12, but the end cross member 12 has a lightening hole 16 already formed at a position where a new rivet hole is to be formed. 16 may be formed.

  In this respect, the support 20 includes a setting plate 21 and a spacer 22 in addition to the license plate bracket 23. Since the license plate bracket 23 is joined to the spacer 22, the display position of the license plate 72 can be changed depending on the position of the rivet hole 53 formed in the spacer 22. Therefore, since the existing end cross member 12 can be used without additional processing, the display position of the license plate 72 can be changed more reliably while reducing the cost.

  (9) Since the first shaft hole 36 has a smaller diameter than the second insertion hole 37, the dimensional error when the first bolt 28 is joined to the setting plate 21 can be reduced. Further, since the dimensional error of the first bolt 28 is reduced, the positional deviation of the second insertion hole 37 with respect to the second mounting hole 19 can also be reduced.

  (10) Since the second shaft hole 46 has a smaller diameter than the first insertion hole 45, a dimensional error when the second bolt 30 is joined to the base plate 42 can be reduced. Further, since the dimensional error of the second bolt 30 is reduced, the positional displacement of the first insertion hole 45 with respect to the first mounting hole 18 can also be reduced.

In addition, the said embodiment can also be suitably changed and implemented as follows.
-The surrounding part should just surround the site | part located between the base plate 42 and the attachment board 48 among the 1st fastening members 26, for example, is comprised with the some columnar body located around the said site | part. May be. For example, you may comprise only the upper facing piece 43 and the lower facing piece 44 of the base member 40, ie, a connection piece. In this case, since the first insertion hole 45 is formed at a position closer to the center in the extending direction of the base member 40, the operation range of the tool passing between the base plate 42 and the mounting plate 48 is effectively limited. can do. Further, when the first nut 29 is a hexagonal nut, the angle formed by the right end of the upper facing piece 43 and the right end of the lower facing piece 44 with respect to the center point of the first insertion hole 45 may be less than 60 °. preferable. According to such a configuration, it is possible to make the loosening operation with the tool inserted from the right opening 55 difficult.

  The spacer only needs to have a base plate, a mounting plate, and a connecting piece that connects the base plate and the mounting plate, and is composed of the base member 40 and the mounting member 41 like the spacer 22 described above. Not limited to those.
