<4. Anti-theft structure>
The anti-theft structure included in the mounting structure of the second vehicle-mounted device 4 will be described. FIG. 16 is a schematic perspective view showing a state in which the first member 51 and the second bracket 62 are attached to the attachment portion 1. FIG. 17 is an enlarged view of a portion surrounded by the broken line frame of FIG.

As described above, the mounting structure of the second vehicle-mounted device 4 has a bracket 6 to which the second vehicle-mounted device 4 is mounted while being mounted on the mounting portion 1 using a fixing member. In the present embodiment, the bracket 6 is divided into a first bracket 61 and a second bracket 62. As shown in FIGS. 16 and 17, the second bracket 62 is fixed to the mounting portion 1 by using the fixing member 9.

The first member 51 is provided with a blindfold portion 515 that covers at least a part of the fixing member 9 in a plan view from one side in the front-rear direction to the other side. In the present embodiment, as shown in FIG. 17, most of the fixing member 9 is covered with the blindfold portion 515 of the first member 51 in a plan view from the rear side to the front side. Therefore, even if the second panel 5 is removed, the blindfolded portion 515 of the first member 51 becomes an obstacle, the fixing member 9 cannot be removed, and the second bracket 62 cannot be removed from the mounting portion 1. .. This makes it difficult to remove the second vehicle-mounted device 4 from the mounting portion 1 and steal it.

Of the plurality of fixing members used for fixing the second vehicle-mounted device 4 to the mounting portion 1, at least one is preferably a special fixing member that requires a dedicated tool. This makes it difficult to remove the second vehicle-mounted device 4 from the mounting portion 1 and steal it. In the present embodiment, examples of the fixing member used for fixing the second vehicle-mounted device 4 to the mounting portion 1 include the following three types of fixing members.

The first fixing member is a fixing member 91 (see FIG. 13) that connects the second vehicle-mounted device 4 and the first bracket 61. The second fixing member is a fixing member 92 (see FIG. 16) that connects the mounting portion 1 and the second bracket 62. The third fixing member is a fixing member 93 (see FIG. 13) that connects the first bracket 61 and the second bracket 62. In the present embodiment, the third fixing member 93 is a special fixing member that requires a special tool. That is, the first bracket 61 and the second bracket 62 are fixed by a special fixing member 93 that requires a special tool. As a result, the connection between the first bracket 61 and the second bracket 62 can be prevented from being easily released. The third fixing member 93 is provided at least one on each side. At least one of the plurality of third fixing members 93 may be a special fixing member.

Then, a person who intends to steal the second in-vehicle device 4 attempts to remove any one of the first fixing member 91, the second fixing member 92, and the third fixing member 93. This is because if any one of them can be disconnected, the second in-vehicle device 4 can be stolen.

However, it is difficult to remove the first fixing member 91 with a tool because the mounting portion 1 is an obstacle. Therefore, it is difficult to release the connection between the second vehicle-mounted device 4 and the first bracket 61 to steal the second vehicle-mounted device 4. There may be a space for removing the first fixing member 91. In this case, it is preferable that the first fixing member 91 is also a special fixing member that requires a special tool. That is, it is preferable that the second in-vehicle device 4 is fixed to the first bracket 61 by a special fixing member that requires a special tool. As a result, the connection between the first bracket 61 and the second vehicle-mounted device 4 can be prevented from being easily released. When there are a plurality of first fixing members 91, at least one of the plurality of first fixing members 91 may be a special fixing member. When the bracket 6 is not divided into a plurality of parts, the second vehicle-mounted device 4 may be fixed to the bracket 6 by a special fixing member that requires a special tool.

A special fixing member 93 is used for the third fixing member 93. Therefore, it is difficult to disconnect the first bracket 61 and the second bracket 62 to steal the second vehicle-mounted device 4.

At least one of the second fixing members 92 cannot be easily removed because it is obstructed by the blindfold portion 515 of the first member 51. The first member 51 cannot be removed unless the second vehicle-mounted device 4 is removed from the storage space 10. Therefore, it is difficult to release the connection between the mounting portion 1 and the second bracket 62 to steal the second vehicle-mounted device 4. A special fixing member that requires a special tool may also be used for the second fixing member 92. However, since the price of the special fixing member is high, it is preferable not to use the special fixing member in consideration of the cost.

From the above, according to the mounting structure of the second vehicle-mounted device of the present embodiment, the second vehicle-mounted device 4 cannot be easily stolen even if the use of a special fixing member is minimized.
