PROBLEM TO BE SOLVED: To enhance the re-usability of the outer constituent parts by preventing the breakage of the outer constituent parts through the mounting parts as caused by the loads working thereon. SOLUTION: A pachinko game machine 1 has an outer frame 2 as an outer constituent part and a front frame 3 provided on the front part. A glass door frame 4 is provided on the front side of the front frame and a game board 5 is arranged at the inner portion. As the premise, the front frame 3 should be openably supported through the mounting parts. Especially, the mounting parts herein used have intended breakage parts easily broken respectively. In other word, it is so arranged that the mounting parts can be broken before the outer frame 2 when unexpected loads work thereon. COPYRIGHT: (C)2005,JPO&NCIPI
