<P>PROBLEM TO BE SOLVED: To provide a game machine capable of continuously smoothly opening/closing a winning hole in a structure for opening/closing the winning hole by transmitting the drive force of a solenoid to engagement projections on the rear surface of opening/closing pieces. <P>SOLUTION: The opening/closing pieces 73 and 74 are formed of a transparent synthetic resin material, whereby an engagement part with a drive transmission member, that is, the engagement projection to receive the drive force of the solenoid via the drive transmission member, can be transparent, and therefore, whether or not bubbles are included in the engagement projections of the opening/closing pieces 73 and 74 made of the synthetic resin material can be discriminated in the manufacturing stage of a variable winning device 70. Accordingly, defective products including bubbles in the engagement projections to reduce the strength of the engagement projections can be sorted and removed in the manufacturing stage, and the manufacturing quality of the variable winning device 70 can be improved. As a result, the variable winning device 70 can be continuously smoothly opened/closed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
