PROBLEM TO BE SOLVED: To provide a Pachinko game machine having a structure wherein a crime prevention effect is improved at an open side part where a fraudulent implement can be most easily inserted from a gap between a main body frame and a door frame. SOLUTION: Since a reinforcing sheet metal 163 is attached along the vertical direction of the back surface of the open side part of the door frame 5, and bent projection pieces 173 and 174 on the outer side and on the inner side, where both long side ends of the reinforcing sheet metal 163 are bent to the rear part, are projected, the metallic bent projection piece 173 can not be cut or destroyed even if a sharp and thin fraudulent implement is inserted from the gap of the door frame 5 and the main body frame 3. Thus, in order to insert the fraudulent implement such as a piano wire, it is necessary to be surely inserted into a meandering gap formed by a recessed part 34 and the metallic bent projection piece 173 inserted into the recessed part 34. Also, even when it is luckily inserted to one meandering gap, it is difficult to insert it to a meandering gap by another recessed part 35 and the bent projection piece 174 of a large projection dimension existing ahead, and the crime prevention effect is extremely high.
