PROBLEM TO BE SOLVED: To provide an input operating device capable of simplified assembly in which a volume mechanism for prolonging the life of a volume is incorporated. SOLUTION: In a volume mechanism part 8', a print circuit board 22 to which a volume 21 is mounted is fixed and integrated through a screw 29 with a bearing part 25. A rotary shaft 27 is inserted into the bearing part 25. The top end of the rotary shaft 27 is provided with a protruding part 28, and inserted and fixed to one end of a flexible joint 24. The top end of the volume 21 is inserted and fixed to the other edge of the flexible joint 24 so that the volume 21 can be connected through the flexible joint 24 with the rotary shaft 27. A contact part 23 of the bearing part 25 with the print circuit board 22 is positioned by not only the screw 29 but also a safety lug 26 so that precise mounting can be realized. |
