PROBLEM TO BE SOLVED: To provide a hinge structure to install a front door frame openably and closably to the outer frame body of a pinball machine which is capable of installing the front door frame from a horizontal direction or a vertical direction. SOLUTION: The hinge shaft 15 of a hinge to open and close a front door body is rotatably supported by a hole-shaped part which is provided for a hinge shaft receiving body and is formed by combining a lock engaging recessed part 44 and a shaft guiding part 20 while a lock recessed part 38 and a lock protruded part 33 are in an engaged state. Therefore, it is possible to remove the front door frame in a horizontal direction by releasing the engagement. In addition, as the hole-shaped part is opened so as to be insertable from a vertical direction, it is possible to install the front door frame from a vertical direction. |
