PURPOSE:To prevent an electric cord from being damaged at the time of opening/closing the lid body of the portable telephone set by preventing the lid body from being closed with great force in the full open state. CONSTITUTION:At one terminal part of a main body 10 of a speaker, a pair of fitting pieces 40 and 40 are installed so as to be moved in the pivotal shaft of a lid body 20, and a shaft 50 is projected from the respective fitting pieces 40 to the side direction. A pair of bearings 21 and 21 are projected from the lid body 20 pivotally supported by the main body 10 of the speaker, and the bearings 21 are faced to the head part of the shaft 50. A projection 70 is protruded from the bearing 21, and an escape groove and a lock groove to be fitted to the projection 70 in the state of completely closing and opening the lid body 20 are formed on the head face of the shaft 50. An electric cord 91 to connect a transmission microphone 90 of the lid body 20 and the main body 10 of the speaker passes a through hole 51 bored at the shaft 50. |
