PURPOSE:To improve durability of a heavy front frame and the strength of a mounting part of a bearing metal by a method wherein a front side body of a single swing front frame supported openable through a hinge is made of a resin and the rear peripheral part thereof is reinforced with a reinforcing frame made of metal, on which the bearing metal is provided. CONSTITUTION:A game machine such as a pachinko (Japanese pinball) machine is provided with a heavy front frame 100 which is mounted openably through hinges 190 with various parts for games arranged therein. The hinges are disposed at upper and lower positions on a front opening part of a body case 200 composing the rear outside diameter of the apparatus. In this case, the front body of the front frame 100 is made of a resin and the rear peripheral part of the body is reinforced with a reinforcing frame 130 made of metal with a U-shaped cross section considering the strength thereof. Then, bearing members 136 are mounted separately at upper and lower position of one side of the rear of the reinforcing frame 130 and a support shaft 191b of the bearing metal 191 mounted at upper and lower ends of the side wall in the front opening of the body case 200 is fitted into a shaft insertion hole 136a to bear the front frame 100. |
