SOLUTION: A first fixing device 25 and a second fixing device constituting a lock mechanism are provided in a ball passage 23 and a game board 4 respectively. When a control circuit unit integrally assembled with respective control circuit boards and the ball passage 23 is attached to the game board 4, a lock portion 25a of the first fixing device 25 is inserted into an opening 31a of the second fixing device with the first fixing device 25 retained in an attachment position. After that, the first fixing device 25 is rotated from the attachment position to a retaining position, so that the first fixing device 25 and the second fixing device are engaged with each other and the control circuit unit is fixedly retained in the rear surface of the game board 4.
