PROBLEM TO BE SOLVED: To provide a transparent plate unit for a game machine which improves the work efficiency and improves the accuracy in sealing of gap space by simplifying the work process.SOLUTION: The transparent plate unit 10 covering the front surface of a game board 6 includes an annular holder frame body 15 having a window 11, and a pair of front and rear transparent plates 9 attached to both surfaces of the annular holder frame body 15 to close the window 11 and to form the gap space S in the middle. The transparent plate unit also has a housing chamber 23 for housing a humidity absorber 22 from an insertion hole 21 disposed on the inner peripheral surface of the annular holder frame body 15, and a lid 24 fitted to the insertion hole 21 of the housing chamber 23. The lid 24 has a vent hole 29 bored to make the housing chamber 23 communicate with the gap space, and locking pieces 27 to be locked in the depth direction of the annular holder frame body 15. Locking parts 28 to be locked with the locking pieces 27 are bored through front and rear walls 23a and 23b of the housing chamber 23. The locking parts 28 of the housing chamber 23 are covered by the transparent plate 9 by fixing the transparent plate 9 to the annular holder frame body 15to seal the gap space S. |
