PROBLEM TO BE SOLVED: To provide a Pachinko machine whose guide rails are easily attached/detached for improved recycling of constituting parts. SOLUTION: A stepped hole 32 is formed in a plywood board 10, and a guide rail attaching pin 30 is inserted into the hole 32. A female screw 45 is formed in the guide rail attaching pin 30. A screw-washer assembly 47 is screwed into the female screw 45 to detachably hold the guide rail 11 on the plywood board 10. When the guide rail 11 is harmed and to be renewed, the guide rail 11 holding the guide rail attaching pin 30 can be easily detached from the plywood board 10 by removing the screw-washer assembly 47 from the guide rail attaching pin 30. Accordingly, no unnecessary force to cause a break is applied to the plywood board, and the quality of the plywood board 10 is not hurt to enable the plywood board 10 to be recycled.
