れ、電気的に絶縁されて取り付けられた状態になる。FIG. 2 shows a state in which an FDD (floppy disk drive) is electrically insulated and attached to a mounting plate via an insulating bush. The mounting hole 11 of the FDD 12 is formed near the edge of the mounting plate 13. If that is not possible, a through hole or a notch through which this insulating bush can pass may be provided near the mounting hole 11. The connecting portion 3 is bent so as to bypass the edge portion of the mounting plate 13 described above. In this way, the outer bush 1 is inserted from the FDD 12 side into the mounting hole 11 of the mounting plate,
The inner bush 2 is pressed into the outer bush 1 from the back surface thereof. Here, the taper part 2e is formed on a part of the step part 2d of the inner bush.
Is preferable and the inlet of the hollow portion 1c of the outer bush is slightly wide, which facilitates press-fitting, which is preferable. After this press-fitting, the stepped portion 2d expands in the large diameter portion of the hollow portion 1c of the outer bush, and is locked and fitted to the stepped portion. Subsequently, the mounting screw 14 is inserted into the hollow portion 2c of the inner bush 2, and is screwed into the screw hole of the FDD 12 and tightened. As a result, the mounting plate 13 and the FDD 12 are separated by this insulating bush, and are in an electrically insulated and mounted state.

As for 12, the mounting plates 13 bent in an L shape are arranged on both left and right sides, and are mounted by the insulating bush 10 as described above. At this time, if the insulating bushes 10 are first attached to all the attachment holes of the attachment plate 13 and then the process is divided so that the attachment screws 14 are tightened, the work efficiency is improved. Furthermore, for mounting to the housing, by screwing this mounting plate 13 etc.
It suffices if the screw head of the mounting screw 14 does not touch the housing. It is needless to say that the insulating bush of this embodiment may be directly mounted in the mounting hole of the housing without using the mounting plate.

ある。In recent years, FDD has become ultra-thin and highly densified, and even a slight mounting distortion may cause an error.
Therefore, it is more preferable to form the insulating bush with a material having elasticity for absorbing the mounting strain and for preventing the earthquake. The fitting of the outer bush and the inner bush in the above-described embodiment is performed by the structure in which the step portion of the inner bush is locked by the step portion of the hollow portion of the outer bush. good. It is also possible to develop the insulating bush into a sheet metal outsert. As described above, the present invention can be variously applied and embodied in accordance with its gist.
