During assembly, the support part 21 of the speaker 2 is brought into contact with the component receiving part 31 of the housing case 3, and the band-shaped fixture 11' is brought into contact with the fixture support part 32. Next, the band-shaped fixture 11' is fastened to the fixture support portion 32 by tightening the screw 13' as a stopper. At this time, the component fixing part 12' extending downward from one end 11'A of the fixture 11' is brought into contact with the support part 21 of the speaker 2, and the support part 21 is pushed down by the downward force of the component fixing part 12'. It is crimped and fixed to the component receiving portion 31.

In order to ensure that the component fixing part 12' provided at one end 11'A of the band-shaped fixture 11' comes into contact with the support part 21, the fixture 11' is placed on an extension of the diameter 2R of the speaker 2 (FIG. 5). It was necessary to provide a positioning means for aligning the axes l of the two. Furthermore, even if the positioning means is used to position the fixture 11, the screw 13' may be tightened.
When tightening the fixture support part 32 with the screw 13'
The fixing tool 11' rotates due to the rotation of the fixing tool 11', and there is a problem in that the axis l of the fixing tool 11', which is aligned with the extension of the diameter 2R, is shifted.

た。 Although only one location is shown in FIG. 5, the mechanical component fixing structure 1' is actually provided at multiple locations on the support portion 21 of the speaker 2. Therefore, the manufacturing cost of the housing case 3 increases by the amount of manufacturing the ribs 33, and the dead space within the device also increases. Furthermore, in the assembly process, the fixture 11' was inserted in line with the recessed portion of the wall 33b, which was inefficient.

As shown in the figure, the housing case 3 includes a component receiving portion 3.
1 and a fixture support part 32 separated therefrom, the fixture 11 is formed into a circular shape, and the circumferential edge is provided with a component fixing part 12 extending downward. When assembling, the support part 21 of the speaker 2
is brought into contact with the component receiving portion 31 of the housing case 3, and the circular fixture 11 is brought into contact with the fixture support portion 32.
Next, the circular fixture 11 is fastened to the fixture support 32 by tightening the screw 13 as a stopper. At this time, the component fixing part 12 extending downward from the circumferential edge of the fixture 11 is brought into contact with the support part 21 of the speaker 2, and the force of pushing down the component fixing part 12 pushes the support part 21 into the component receiving part. 31 is crimped and fixed.

不要である。。 Fixture 11 of mechanism component fixing structure 1 according to the present invention
Since it is formed into a circular shape, the component fixing portion 12 extending downward from the edge is also formed on the circumference. Therefore, if the diameter of the fixture 11 is appropriately selected, the component fixing part 12 will definitely come into contact with the supporting part 21, which is the supported body, and no positioning means such as ribs will be necessary. In addition, even if the screw 13 is tightened, the diameter of the fixture 11
Since 2r is always on an extension of the diameter 2R of the speaker 2, there is no need for any means for preventing rotation of the fixture 11. .

果を奏する。 In the above embodiment, the component fixing part 12 provided on the fixture 11 has been described as extending downward from the circumferential edge of the fixture 11. For example, the height of the fixture support part 32 can be adjusted appropriately. The same effect can be obtained even if the circumferential edge of the fixture 11 itself is used as the component fixing part 12.

コストダウンが計られる。 Mechanical component fixing structures 1 are provided at multiple locations on the support portion 21 of the speaker 2, as in the past, but the ribs 33 are not required, the dead space inside the device is reduced, and the assembly process is simplified and more efficient. It became. Since the fixture 11 is made of synthetic resin, problems such as loosening of the crimped part due to deformation caused by impact, rusting, and short circuits due to contact with electronic components inside the device do not occur, and there is no need for plating, which reduces costs. Down is measured.
