As shown in FIG. 7, the cover 23 of the connector cover 10 is positioned below the battery lid 21 including the mating surface of the connector cover 10 at a position opposite to the position where the tongue 24 is formed (the other end). A cover detachment prevention rib 23c is formed on the key rear case 19 so as to protrude from the upper end portion 23a of the cover portion 23 to the inside of the case so as to close the space s (see FIG. 4A). With this cover removal prevention rib 23 c, the connector cover 10 can easily get over the mating surface with the battery lid 21 and not come off.

The key rear case 19 is provided with a cover presser convex portion 30 that is engaged with the concave portion 10a of the connector cover 10 so as to protrude toward the connector cover 10 side. Instead of the battery lid 21 having a small thickness and lacking rigidity for thinning, the cover pressing convex portion 30 is configured to hold the connector cover 10 and fix the position of the connector cover 10 in the case thickness direction. .
As described above, when removing the connector cover 10, the abutment rib 27 prevents the connector cover 10 from entering the lower surface side of the battery lid 21, thereby improving the operability related to the operation of removing the connector cover 10. To do. Further, since the rib 27 prevents the connector cover 10 from entering the lower surface side of the battery lid 21, the battery lid 21 can be prevented from being lifted.

That is, when the mating surfaces of the battery lid 21 and the connector cover 10 are the same, the opening and closing operation of the connector cover 10 can be performed smoothly by providing the ribs 27 on the battery lid 21. Further, by making the mating surfaces of the battery lid 21 and the connector cover 10 the same, the case can be made thinner.
That is, when the case is thinned, the distance between the connector opening 22 and the bottom surface of the battery lid 21 is inevitably reduced, and the mating surface between the connector cover 10 and the battery lid 21 approaches. In this case, the set thickness may not be reduced due to the thickness of the key rear case 19 sandwiched between the connector cover 10 and the battery lid 21. By making the mating surfaces of the battery lid 21 and the connector cover 10 the same, it is possible to make the key rear case 19 thinner.

Further, by making the mating surfaces of the battery lid 21 and the connector cover 10 the same, the appearance can be shown simply. Further, by providing the battery lid 21 with the rib 27, the connector cover 10 can be opened and closed smoothly. Further, by providing the cover detachment prevention rib 23c and the cover pressing convex portion 30, the connector cover 10, the battery lid 21 and the key rear case 19 are firmly fixed so that the connector cover 10 cannot be easily removed.
