PROBLEM TO BE SOLVED: To provide a butterfly type game machine hinge, in which a clearance between a front door and a casing is eliminated to hold the front door firmly and to retain a high security against a dishonest act.SOLUTION: From a stationary member 1 on the front face side of a vertically long mounting plate portion 2, a bearing plate portion 4 is outwardly bent and extended at an acute angle through a bent arcuate plate portion 3. On the outer end portion of the bearing plate portion, a plurality of stationary bearing portions 5 are formed at a predetermined spacing, and a fixation hole 2b and a temporary stop groove 2a are formed in the mounting plate portion 2. In a movable member 11, movable bearing portions 15 are formed at a predetermined interval on the back side of a vertically long mounting plate portion 12. On the front side of the mounting plate portion 12, there is mounted an arcuate plate portion 13 having a curvature substantially equal to that of the arcuate plate portion of the stationary member, when closed, to overlap the arcuate plate portion of the stationary member. A vertically long protective wall plate 14 having a transverse section bent generally in an L shape is fixed on the outer side of the mounting plate portion 12. |
