In this state, the stop rib 20 is arranged in a state of being substantially in close contact with the rear surface (the inner surface 6b side) of the locking piece 14 (see FIGS. 1 and 10). As a result, the lid 9 is prevented from coming off by the engagement between the locking claw 21 and the end face 16a and the engagement between the locking claw 19a and the lock hole 15, so that the lower cover 5 is closed with the opening surface of the concave portion 6 closed. Fixed.

Accordingly, the attachment of the HDD assembly 8 to the electronic device 1 is completed, and the inner surface 6
Between the b and the locking piece 14, the locking piece 19 and the stop rib 20 are arranged so as to close this gap. In this state, the electronic device 1 receives vibration from the outside, and for example, a force is applied to move the HDD assembly 8 in the direction of arrow B in FIG. In such a case, since the stop rib 20 is disposed on the back side of the locking piece 14, the stop rib 20 functions as a stopper and the locking piece 14
The locking claw 14a and the lock hole 13 are prevented from coming off. Further, the force in the direction of arrow B is also transmitted to the locking piece 19 on the lid 9 side via the stop rib 20 and presses the locking piece 19 against the inner surface 6b.

Next, a case in which the HDD assembly 8 needs to be replaced and the HDD assembly 8 is removed will be described. In this case, a force is applied to the lid 9 to peel the end of the lid 9 on the side where the locking piece 19 is formed outward. Then
Since the locking surface 19b of the locking claw 19a is formed as a tapered surface, the locking piece 19 is elastically deformed inward (to the stop rib 20 side) by the force of pulling the lid 9, and escapes, thereby lifting one side. be able to. Next, when the locking claws 21 are removed from the inside of the slit 16, the lid 9 can be removed from the lower cover 5, whereby the HDD assembly 8 is exposed in the recess 6.

Next, the locking piece 14 is tilted toward the inner surface 6b of the recess 6 to release the locking claw 14a from the lock hole 13, and in this state, one side of the HDD assembly 8 near the locking piece 14 is lifted up. Next, when the locking claw portion 12e of the bracket 12 is pulled out from the notch portion 18 of the lock plate 17, HD
The D assembly 8 can be removed from the inside of the recess 6. Then, the replacement is completed by installing the new HDD assembly 8 as described above.

Therefore, in the structure of this embodiment, the HDD assembly 8 can be easily attached without using screws or the like used in the conventional structure. Further, even if the entire lower cover 5 is not removed, the replacement work can be easily performed simply by removing the lid 9. Further, the inner surface 6 of the recess 6
The lid 9 is closed by placing the locking piece 19 and the stop rib 20 in a state where the gap between the b and the locking piece 14 is closed.
The assembly 8 can be prevented from easily coming off.

In this embodiment, the HDD assembly is an HD
The case where the HDD unit 10 is composed of the D unit 10 and the bracket 12 has been described. However, this is also applicable to the case where the HDD unit 10 is directly incorporated in the concave portion 6.
A similar effect can be expected when the present invention is applied to a case where a unit product that needs to be replaced, such as a battery unit, is attached to the electronic device 1 without being limited to the DD assembly 8.
