PROBLEM TO BE SOLVED: To prevent a lock device of a Pachinko machine from being unlocked illegally. SOLUTION: In this lock device of the Pachinko machine, a movable locking plate mounted on a door is slid in the unlocking direction by a lock mounted on the door to detach a locking claw interlocking with the movable lock plate from a receiving metal fitting mounted on the other door, thereby unlocking one door. The movable locking plate is stored in a locking plate case 12 fixed to one door. Accordingly, even if a thin plate-like special tool is inserted from a gap between one door and the other door, the special tool is interrupted by the locking plate case 12 not to come into contact with the movable locking plate. Thus, the movable locking plate will not be moved by the special tool.
