PROBLEM TO BE SOLVED: To provide a double glass body reducing collision sound of Pachinko balls. SOLUTION: A front face door 30 is formed of synthetic resin and fitted with a double glass body 40. The double glass body 40 is so constituted that two glass panes are retained with a predetermined interval apart by a retaining frame body formed of an elastic body. A collision sound reducing member 50 is disposed between the two glass panes of the double glass body 40 for mitigating the collision impact of the Pachinko balls and reducing the collision sound.
