DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an assembly view showing an embodiment of the present invention, and FIG. 2 is a sectional view after assembly. A lower case 1 has a first concave portion 1A formed at the upper end thereof. Reference numeral 2 denotes an upper case, at the lower end of which is formed a second recess 2A. Numeral 3 denotes a cable fixing bush that sandwiches (or inserts) the cable 4, and the first concave portion 1A and the second concave portion 2A.
A flange portion 3A having a larger outer shape, and a flange portion having a gap substantially equal to the thickness of the upper end portion of the lower case 1 and substantially the same outer shape (bottom portion) as the contour of the first concave portion 1A. The lower case engaging portion 3B formed on the lower case 3A has a gap substantially equal to the sum of the thickness of the upper end of the lower case 1 and the thickness of the lower end of the upper case 2; A lower / upper case engaging portion 3C is formed on the collar portion 3A so as to have substantially the same outer shape (bottom portion).

FIG. 2 shows an electric device assembled by a lower case 1 and an upper case 2 using a cable fixing bush 3. The electric device has a first concave portion 1 A formed at an upper end of the lower case 1. A second concave portion 2A formed at a lower end portion of the upper case 2, and a cable fixing bush 3 including the collar portion 3A, a lower case engaging portion 3B, and a lower / upper case engaging portion 3C. .

According to this embodiment, the lower case 1 having the first concave portion 1A and the upper case 2 having the same second concave portion 2A can be formed by using the cable fixing bush 3 by a simple notch. The first concave portion 1A of the lower case 1 is engaged with the lower case engaging portion 3B of the cable fixing bush 3, and the first concave portion 1A of the lower case 1 and the upper case 2 are engaged with the lower / upper case engaging portion 3C of the bush 3. The second concave portion 2A is engaged to assemble the electric device, so that rattling can be eliminated. The lower case 1 and the upper case 2 are provided with the first recess 1A by a simple method.
In addition, the labor for forming the second recess 2A is not required.

FIG. 3 shows another embodiment of the present invention.
The flange 3A is provided at the end of the second recess 2A of the upper case 2.
And a wide portion 2B substantially identical to the outer shape of the wide portion 2B.
B is located at a portion adjacent to the lower case engaging portion 3B.

Instead of providing the wide portion 2B shown in FIG. 3, the side portion of the second concave portion 2A is directly extended downward, and the lower / upper case engaging portion 3C of FIG. 1 is also extended downward as it is. You may do it.

[0016]

As described above, according to the present invention, it is possible to provide a cable fixing bush and an electric device using the bush, which eliminates backlash and simplifies processing of a case.
