PROBLEM TO BE SOLVED: To provide a board box of a pachinko game machine capable of being securely sealed by a simple structure. SOLUTION: The board box is provided with a locking hole part 18 facing a side of a box body 1 via a connection part 7 for a cut on one side of a plate body 2. A key function part 3 consisting of an anti-reversing member 9 into which a locking pin 8 is inserted is provided on a side of the box body 1 where the locking hole part 18 is placed. Pushing out the locking pin 8 to insert the front end thereof into the locking hole part 18 restricts a slide of the plate body 2 to seal the box body 1. The locking pin 8 is provided with a shaft part 81 having right/left elastic catches 82 protrusively provided. The anti-reverse move member 9 is provided with groove parts 91 into which the locking pin 8 is inserted. Recess parts 92 into which the elastic catches 82 are fit are formed on the sides of the groove parts 91, enabling the locking pin 8 to move in only one direction. COPYRIGHT: (C)2005,JPO&NCIPI
