PROBLEM TO BE SOLVED : To provide a lock mechanism for a Pachinko game machine (including a Pachinko slot game machine) being an inexpensive, easily assebling integrated and compact illegal-unlock preventing mechanism with which the door of the game machine is not unlocked by a person other than a hall manager and an illegal release is prevented surely. SOLUTION : In a key mechanism body 10, a hook bracket and a lock bracket are firmly caulked to a base bracket at designated positions for unification in order to save space and to achieve compactness. Then unification is performed to provide an integrated configuration. A confronting fixing bracket for cramping is incidentally attachable to the main body of a game base, having a slide-adjustable attachment board required for positioning, so as to be freely attachable. Thus, a key lock mechanism is widely adopted to the Pachinko game machines (including the Pachinko slot game machine) in general. Transition by the performance in an early stage provides not a little expectation to an earth-conscious industry form. By the form of the present invention, the mechanism has possibility to be controlled by fixing an electric motor without the insertion of a key from an outer part in the future. The mechanism may be remotely controlled by immediate correspondence in the case of the needs from market. Moreover, A security cover can be attached onto the hook bracket and the lock bracket, etc., so as to prevent an illegal operation from a rear surface in consideration of a security problem.
