PROBLEM TO BE SOLVED: To provide a locking device for a front face frame for preventing intentional release of a locking condition of a hook piece carried out through a partial change in a cylinder lock arranged in a conventional pachinko machine without using a key for the cylinder lock. SOLUTION: If an elevating lever 16 is tried to be moved upward intentionally without using the key for the cylinder lock 20, an upper end part of a lock release piece 17 arranged in the elevating lever abuts on a stopper piece 29 in a second cam 27 and prevents a shift of the elevating lever 16, and consequently, the locking condition of the hook piece 14 with a latching piece 3 is maintained.
