Next, an assembling procedure of the first embodiment will be described with reference to FIGS. 1, 2 and 3.

The fitting recess 1c of the non-slip belt 1 is
The outer wall 2a of the case 2 is fitted into the fitting groove 1b of the non-slip belt 1 while being joined to the protrusion 2c, and the non-slip belt 1 is fixed to the case 2; The outer wall 3a of the cover 3 is engaged with the fitting groove 1 of the anti-slip belt 1 while the inner wall 2b of the L-shaped tip of the case 2 is engaged.
b, and the non-slip belt 1 is fixed by being sandwiched between the case 2 and the cover 3.

As described above, in the first embodiment, the non-slip belt 1 is integrated with the protective cover 1a,
Two parts become one part and the number of parts can be reduced,
Since there is no screwing, assembly man-hours can be reduced. In addition, since there is no boundary between the non-slip belt 1 and the protective cover 1a by being integrated with the protective cover 1a, a degree of freedom in design can be secured.

Further, since the joint between the case 2 and the cover 3 is on the back side of the non-slip belt 1, the joint between the housings does not touch the hand, so that the feeling of hand and the appearance quality are improved. Can be.

FIG. 4 is an exploded perspective view showing a second embodiment of the present invention, and FIG. 5 is a cross-sectional view showing an engaged state of a non-slip belt according to the second embodiment.

A case 5 having a mating groove 5a, a fitting groove 6a similar to the case 5, and a protective cover 7 for an electric component such as an earphone jack.
The cover 6 having the engaging rib 6b for engaging the slip-off preventing rib 7a is fixed by being sandwiched, and the protective cover 7 is engaged with the engaging rib 6b of the cover 6 and the slip-off preventing rib 7a. It is structured to be fixed by being sandwiched between the cover 5 and the cover 6.

[0018]

As described above, according to the present invention, there is provided a fitting groove provided around a side surface of a cover and a case, which constitute a housing of a device, engaging with the first and second fitting grooves. It has a non-slip belt provided with a protective cover for protecting external connection electrical components, a first fitting groove for inserting the non-slip belt, and a first inner wall supporting the non-slip belt. By providing a cover, a case having a protrusion for fixing the protection cover of the anti-slip belt, a second fitting groove similar to the cover, and a second inner wall, there is no step of fixing with a screw. This has the effect of reducing the number of assembly steps.

Further, since the end surface of the anti-slip belt is outside the case and the cover, and the case and the cover are also on the back side of the anti-slip belt, the gap between the case and the cover can be prevented. This has the effect of improving the appearance quality as compared with the conventional one, with a good feel when touched.
