Thereafter, the operation projection 44 is slid toward the short side 15d of the opening 15 to slide the lock frame 40 toward the short side 15d in the groove 18. Then, as shown in FIGS. 14A to 14I, the engagement protrusion 45 of the lock frame 40 meshes with the groove 36 of the lid 30 (see FIG. 14H). At the same time, the engaging step portion 46 of the lock frame 40 engages with an engaging claw 64 formed on the outer peripheral surface of the inner peripheral wall portion 17 at the short side 15a (see FIG. 14I).
The protrusion dimension S1 of the engagement protrusion 45 is smaller than the protrusion dimension S2 of the engagement step portion 46. For this reason, after the engagement of the engagement step portion 46 and the engagement claw 64 is preceded and the lock frame 40 is engaged with the rear housing 11B, the engagement protrusion 45 and the groove 36 are engaged, and the lock frame 40 is engaged. The lid 30 can be engaged.
At the same time, as shown in FIGS. 14F and 14G, the engagement hook 43 of the lock frame 40 engages with the engagement claw 35 formed on the back surface 31 a of the lid 30. Specifically, the parallel wall portion 35 b of the engagement hook 43 and the parallel wall portion 35 b of the engagement claw 35 are inserted by inserting the parallel wall portion 35 b of the engagement claw 35 into the engagement groove 43 c of the engagement hook 43. Are in a state of facing each other. This restrains the face plate 31 of the lid 30 from being displaced in a direction away from the surface 11r of the rear housing 11B.

As a result, the lid 30 is provided with the engagement protrusion 45 located on the short side 15a of the opening 15 and the engagement hook 43 located on the

long sides

15b and 15c, and the rear side of the lid 30 via the lock frame 40. It will be in the state which is fixed to the housing 11B and cannot be removed from the opening part 15. FIG. Thereby, the lid 30 is firmly fixed, and the face plate 31 can be prevented from being bent. Accordingly, it is possible to reliably prevent the lid 30 from falling off and to reliably exhibit the waterproof property by the seal ring 33.
Further, the lid 30 can be reliably fixed by one operation of sliding the lock frame 40.
Furthermore, since the lid 30 can be fixed on three sides by one lock frame 40, the above-described effects can be obtained at low cost.
Further, the lock frame 40 that can be visually recognized from the appearance of the mobile phone terminal 10 is only the operation protrusion 44. Since the shape of the operation projection 44 is not different from the conventional lid lock structure, the degree of freedom in design is not impaired.
