<P>PROBLEM TO BE SOLVED: To provide a vertical frame member for an outer frame of a Pachinko machine, which can be assembled in a less number of steps, has a sufficient strength and can constitute the Pachinko machine with a large-sized front frame and a game machine. <P>SOLUTION: A rectangular metallic plate 10 is bent along its longitudinal direction by a plurality of times, while one end side edge 12a and the other end side edge 12f of the folded ends in the sort-length direction of the metallic plate 10 are overlapped to each other, so as to have a caulking 30. In particular, the plate is bent back by 180° from a predetermined folding part 14c along its longitudinal direction, and an inner side 12c and an outer side 12d are made as a double-overlapped portion 31. A substantially oval depression and a substantially circular depression formed in advance in the longitudinal direction of the outer side 12d are made as a substantially-oval-shaped contact part 3Aa and a substantially-circular-shaped contact part 3Ab at the double-overlapped portion 31, respectively. Further, the surrounding area of the contact parts 3Aa, 3Ab is made as a clearance part 3Ac at the double-overlapped portion 31, thereby forming a caulking 3J with the contact parts 3Aa, 3Ab to constitute the vertical frame member 3A. <P>COPYRIGHT: (C)2012,JPO&INPIT |
