PROBLEM TO BE SOLVED: To provide a pinball game machine configured to prevent fraudulent opening of a lid if a piano wire is inserted into a play zone, and configured to easily and inexpensively provide such a preventive structure as above. SOLUTION: Even if a piano wire or the like is inserted by a fraud doer into the play zone, and the lid 5a of an attacker 5 is pulled in the direction of opening by the piano wire or the like, the motion of the lid 5a in the direction of opening is restrained by the locking of an engagement recess 55d with a projection 57 of an L-shaped link 56. Accordingly, the inconvenience caused by the fraudulent opening of the lid 5a can be effectively prevented, and an effective measure against the fraudulence can be provided by such a simple and inexpensive configuration as locking a part of a motion converting mechanism only.
