PROBLEM TO BE SOLVED: To provide a locking system for a pachinko machine, which can prevent the fraudulent unlocking from occurring by a simple mechanism. SOLUTION: A glass frame locking rod 12 to lock a glass frame 22, which is openably provided in a front surface frame 21, is slidably arranged in a base frame body 1. When the glass frame 22 is closed, the free end section of the glass frame locking rod 12 is located in a manner to cover an attaching plate 2 of the base frame body 1. An opening lever 13 which urges the glass frame 22 to the opening side is pivotally supported by the attaching plate 2 in a manner to be turnable. Then, an engaging protuberance 4c is formed on a connecting rod 4 in a manner to project to the front surface side of the base frame body 1 from a slit 2c formed on the attaching plate 2. When the glass frame 22 is closed, and the opening lever 13 is turned inward, the engaging protuberance 4c comes into contact with the opening lever 13, and prevents the connecting rod 4 from moving to the unlocking side.
