PROBLEM TO BE SOLVED: To provide a sealing structure for game machines capable of reducing backlash of a sealing member fitted in a sealing object hole.SOLUTION: The sealing structure for game machines is so configured that an engagement part A provided at a sealing member 100 and an engagement part B provided at a sealing object member 200 are mutually engaged so as to lock the sealing member 100 fitted in a sealing object hole 210. The sealing structure includes a gap infilling displacement part C at least at any of an inner peripheral part of the sealing object hole 210 and an outer peripheral part of the sealing member 100. In a halfway engagement state where the engagement part A and the engagement part B are halfway through the engagement, the gap infilling displacement part is displaced to a retraction position not inhibiting the engagement between the engagement part A and the engagement part B, however, in an engagement completion state where the engagement between the engagement part A and the engagement part B is completed, is displaced to a projection position projecting into a gap formed between and engagement surface αand an engagement surface β.SELECTED DRAWING: Figure 9 |
