Then a vertical part 13a of a battery 13 is inserted in a battery container 3 of the front case 1 through a battery insert port 9a at the battery container 9 of the rear case 7 and the horizontal part 13b of the battery 13 is inserted to the battery support 9b of the rear case 7. Then a middle part 15 of the battery retainer spring 14 is locked to a lock rib 4 at the end face of the front case 1, and both ends 16 are fixed to a locking part 10 formed on both sides of the other end face of the battery container 9 of the rear case 7 to retain and fix the battery 13 from the upper part. |
