<p>PROBLEM TO BE SOLVED: To solve the problem that sealing is released because pin receiving plates are drawn out.SOLUTION: In the game machine, the periphery of a through-hole 22b2 for inserting a bolt pin 40 therethrough is covered from outside with a metal protective plate 51, thereby preventing the periphery of the through-hole 22b2 which allows the pin 40 to exhibit restriction, from being broken from outside. The protective plate 51 is formed by extension of pin receiving plates 53a and 53b holding the front ends 42a and 42b of the pin 40 under anti-drawing state. Therefore, when the pin receiving plates 53a and 53b are removed to release the anti-drawing state of the front ends 42a and 42b of the pin 40, the outside protective plate 51 is removed together. Accordingly, a sign that the pin receiving plates 53a and 53b are removed can be easily detected from outside.</p> |
