PROBLEM TO BE SOLVED: To provide a game machine wherein sealing work is facilitated, the history of sealing cancellation is left, the fraudulent exchange of an exchange unit is prevented, and the exchange unit is detachable from a case body by canceling a sealed state by pulling out an insertion arrow blade part from a second hole part. SOLUTION: An insertion hole (121) is formed of a first hole part (123) where the insertion arrow blade part (101) can be deformed and inserted but an insertion part (106) can not be pulled out, and the second hole part (122) where the insertion part (106) can be pulled out by moving the insertion arrow blade part (101) inserted to the first hole part (123) in a specific direction. The area between the exchange unit (40) and the case body (1) is sealed by inserting the insertion part (106) to the first hole part (123), and the sealed state is canceled by destroying an insertion body (100) and making it movable in the specific direction.
