PROBLEM TO BE SOLVED: To easily reinforce an open/close door while suppressing useless reinforcing members, and to reduce manufacturing cost. SOLUTION: One left or right end side of the open/close door 7 through which a game play area 17 of a game board 6 is visible is openably/closably pivotally attached by hinges 9 to game machine bodies 2 and 3, and the other right or left end side of the door is locked in the closed state by locking means 11 to the game machine bodies 2 and 3. The pinball game machine at least includes: a first reinforcing member 32a made of a sheet metal for reinforcing one end side of the open/close door 7; a second reinforcing member 32b made of th sheet metal for reinforcing the other end side of the open/close door 7; and a third reinforcing member 32c made of the sheet metal for reinforcing the lower end side of the open/close door 7. The thickness Tb of the second reinforcing member 32b is thicker than the thickness Ta of the first reinforcing member 32a. A socket 62 with which a latch 84 of the locking means 11 is detachably engaged is integrally formed in the second reinforcing member 32b by a folding process. COPYRIGHT: (C)2011,JPO&INPIT
