<p>PROBLEM TO BE SOLVED: To provide a pinball game machine which can reinforce an opening/closing door easily with a simple structure while suppressing the uselessness of a reinforcing component and can support a transparent plate unit reliably.SOLUTION: A pinball game machine comprises an opening/closing door 6 arranged in openable and closable manners on the front face of a game board 5. The opening/closing door 6 includes a door main body 24 having a window hole 23 formed to correspond to a game area 13 of the game board 5, and a transparent plate unit 27 removably fitted on the back side of the door main body 24 and fitting the window hole 23 in a manner to see through the game area 13. At least included are: a first reinforcing member 38a made of a sheet metal for reinforcing one end side of the door main body 24; a second reinforcing member 38b made of a sheet metal for reinforcing the other end side of the door main body 24; and a third reinforcing member 38c made of a sheet metal for reinforcing the lower end side of the door main body 24. The board thickness Tc of the third reinforcing member 38c is made larger than the board thickness Ta of the first reinforcing member 38a, and the third reinforcing member 38c is integrally formed with a receiving portion 50c for receiving the transparent plate unit 27 from the lower side through bending process.</p> |
