PROBLEM TO BE SOLVED: To solve the problem that sealing is released by getting pin receiving plates drawn out. SOLUTION: In the game machine, the periphery of a through-hole 22b2 in which a bolt pin 40 is inserted is covered outside with a metal protective plate 51, thereby preventing the periphery of the hole 22b2, by which the bolt pin 40 exhibits restriction, from being broken. The metal protective plate 51 is formed by extension of the pin receiving plates 53a and 53b receiving the front ends 42a and 42b of the bolt pin 40 under anti-drawing. Thereby when the pin receiving plates 53a and 53b are removed to release anti-drawing of the front ends 42a and 42b of the bolt pin 40, the outside metal protective plate 51 is removed together. Accordingly a sign that the pin receiving plates 53a and 53b are removed can be easily detected outside. COPYRIGHT: (C)2012,JPO&INPIT |
