PROBLEM TO BE SOLVED: To prevent dispersion in voice power for each user due to personal difference among interval and angle of ears and mouth of persons by forming a cylindrical open/close adjustment member with a notch and fixing the notch of the open/close adjustment member at an optional angle so as to allow each user to adjust a folded angle to be preferred open/close angle. SOLUTION: A projected stripe is formed on an inner face of a cylinder section 3 axially and a cylindrical open/close adjustment member 8 with a notch is formed. The member 8 is inserted into the cylinder section 3 to press one en of the cylindrical open/close adjustment member 8 into contact with an end face of a cylinder section 6 and the other end is tightened by a screw 11 and the notch 10 of the cylindrical open/close adjustment member 8 is fixed at an optional angle. Since the structure of the telephone set to fix it at an optional position preferred by the user is obtained, excellent communication sensitivity is obtained without dispersion in voice power during transmission. Furthermore, even when an excess force is exerted to the telephone set in the case of opening/closing, a damaged turning mechanism is avoided. Moreover, since the open/close angle is adjusted by less number of components, the excellent assembling and maintenance performance are obtained. |
