PROBLEM TO BE SOLVED: To enhance the strength of a glass frame made of a synthetic resin in a Pachinko game machine. SOLUTION: A frame body 32 made of a synthetic resin is provided with an upper side sheet metal 50, a lower side sheet metal 52, a right side sheet metal 54, and a left side sheet metal 56, all of which are bent in a L shape, and attached to a flat part 32A, being joined to the frame shape. This structure prevents the frame body 32 from being bent or strained. Also, since the reinforced surfaces of the upper side sheet metal 50 and the lower side sheet metal 52 are arranged close to the side surface 32B of the frame body 32, it can reduce the deformation or the damage due to external pressure on the side surface 32B.
