6 are provided, and the vehicle-mounted device 1 is
The vertical movement of 1A, 11B, and 11C is regulated. In order to attach these in-vehicle devices 11A, 11B, 11C to the inner frame 3, first, the in-vehicle device 11A is inserted into the lowermost insertion gap until the first heat sink 15 contacts the lower positioning member 4. Next, the in-vehicle device 11B is inserted into the insertion gap above it so that the first radiator plate 16 comes into contact with the second radiator plate 18 of the in-vehicle device 11A. Further, the in-vehicle device 11C is inserted into the insertion space above the first radiator plate 17 so that the second radiator plate 19 of the in-vehicle device 11B is moved.
To make contact. At this time, each first heat sink 15,
Since 16 and 17 have shapes inclined in the insertion direction a, each of the on-vehicle devices 11A, 11B and 11C is in a state where it has not reached the predetermined mounting position. Therefore, the three on-vehicle devices 1A, 11B, and 11C are pushed in until the second on-vehicle device 11C of the on-vehicle device 11C comes into contact with the upper positioning member 5, so that the three on-vehicle devices 1A, 11B, and 11C are pushed.
It reaches a predetermined mounting position against the repulsive forces of 6, 17. In this state, the screw fixing part 1 of the vehicle equipment 11C
By fastening the internal frame 3 and the inner frame 3 with the screws 22, 22, all three on-vehicle devices 11 A, 11 B, 11 C can be attached and fixed. Of course, all the in-vehicle devices may be fixed with screws. Finally, by attaching the bezel 7 having the opening 7a as shown in FIG. 6 so that the operation surface of each vehicle-mounted device is exposed, the installation of the device is completed.

Conversely, in the in-vehicle device 11B, heat can be released to the in-vehicle device 11C through the contact between the in-vehicle device 11A or the second radiator plate 19 and the first radiator plate 17. Similarly, in the vehicle-mounted device 11C, heat can be released to the vehicle-mounted device 11B or the upper positioning member 5 side. For example, in an in-vehicle audio device, when using a cassette player, C
Since a D player or the like is not used at the same time, it is effective to release heat to other in-vehicle devices. As described above, in the present embodiment, since the positioning function and the heat radiation function are provided by the first and second heat radiation plates, the mounting operation becomes extremely easy without complicating the structure of the vehicle-mounted device. In particular, the fixing with the screw 22 may be performed only with at least the uppermost on-vehicle device 11C, and the on-vehicle devices 11A, 11B, and 11C can be easily attached and detached.

Although the present embodiment has been described above, the present invention is not limited to this, and various design changes accompanying the gist of the configuration are possible. For example, in the above-described embodiment, the first heat sink is inserted in the insertion direction a more than the second heat sink.
Although it is set to be located on the rear side, the second heat sink may be located on the rear side of the first heat sink in the insertion direction a. Conversely, in this case, the uppermost in-vehicle device 11C is first placed. Just insert it. Further, in the present embodiment, the present invention is applied to a structure in which three in-vehicle devices are attached, but the number of in-vehicle devices is not limited to three.
