PROBLEM TO BE SOLVED: To facilitate gap management in the case of manufacture and to prevent the battery pack from coming off by reducing a play cased when the battery pack is mounted. SOLUTION: A fixed projection 10 and a positioning projection 8 are provided to a mount 4 of a telephone set main body, and 1st, 2nd recessed parts 21, 22, an engagement recessed part 9 and a positioning recessed part 11 are provided to a battery pack 3. A container part 15 is formed to a case 13, which contains a slide hook 20 provided with 1st and 2nd projections 23, 24 and a spring 14 that energizes the slide hook 20 is direction of the battery pack to produce a pressing force. The battery pack 3 is mounted by inserting the engagement recessed part 11 to the fixed projection 10 and moving a contact to a fulcrum shaft, while drawing a rotary orbit to fit the positioning projection 8 to the positioning recessed part 9. Furthermore, a slope 24a of the 2nd projection 24 is pressed into contact with the 2nd recessed part 22, a pressing force is divided into the lengthwise direction and the broadwise direction, to eliminate a play of the battery pack 3. Furthermore, the battery pack 3 is prevented from coming off by an external factor through an engagement between planes 23a, 21a of the 1st projection 23 and the 1st recessed part 21. |
