PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can prevent breakage of a cold cathode tube as caused by vibrations in a structure with the cold cathode tube mounted on the door frame. SOLUTION: Electrode insertion holes 126 are formed respectively in electrode support parts 125 for supporting both ends of the cold cathode tube 132 and sleeves 133 made of a rubber mounted at the respective end parts of the cold cathode 132 are supported by the electrode insertion holes 126 to be loosely fitted. Even when the cold cathode tube 132 is vibrated by an impact or the like, the end parts of the cold cathode tube 132 oscillate or slide respectively at the electrode support parts 125 to weaken the destructive stress in the absorption of the vibration with the rubber sleeves 133, thereby preventing the breakage of the cold cathode tube 132 at the respective electrode support parts 125.
