PROBLEM TO BE SOLVED: To simplify the structure of a transparent plate holder for a pachinko game machine and reduce the numbers of parts and manufacturing processes. SOLUTION: Although glass plates 32a and 32b are normally inserted in glass grooves 26a, 26b, 28b, 30a and 30b in vertical rails 26, 28 and in a lateral rail 30 of a glass holding door 10, an upper side restriction portion 34 is set back from the upper sides of the glass plates 32a and 32b when the glass holding door 10 is opened, preventing the restriction of the glass plates 32a and 32b to be moved up. A protruded portion 24 is also set apart from a cutout portion 22, so that the glass plates 32a and 32b can be passed through the cutout portion 22. The glass plates 32a, 32b can be pulled out or inserted in along the glass grooves 26a, 26b, 28b, 30a and 30b. No oscillatable displacement of the vertical rails 26 and 28 is required for pull-out and insert-in, resulting in a simple structure and less numbers of parts and manufacturing processes.
