PROBLEM TO BE SOLVED: To provide a game machine provided with an outer frame which is excellent in environmental preservation, can reduce a manufacture cost and has sufficient strength even when thinned. SOLUTION: The outer frame 12, has four sides separately provided and the respective sides are composed of extrusion materials 12a-12d made of alluminum. The extrusion materials 12a-12d are composed of a hollow cylinder whose cross section is rectangular. The extrusion materials 12a-12d are formed by cutting one extrusion material by the length of the respective sides and executing work to each of them. The extrusion materials 12a-12d are connected by connection plates 20a-20d, and the connection plates 20a-20d are composed of a sheet metal bent so as to be a substantially L-shape along two adjacent sides of the outer frame 12. Timber 22 is inserted to the extrusion materials 12a-12c and the inserted timber 22 is exposed from an opening 25 for exposing the timber. Thus, nails can be driven when carrying and installing a pachinko game machine. COPYRIGHT: (C)2007,JPO&INPIT
