To prevent a connection cable 70 from dropping off when a front face frame 60 is opened.

A Pachinko game machine includes the connection cable 70 provided with an extensible helical part 72, a first line part 74a and a second line part 74b capable of rotating with an opening of the front face frame 60, which allows the extensible helical part 72 to expand and contract due to its resilient deformation and the first line part 74a and the second line part 74b to rotate to a helical axis 71 of the extensible helical part 72 in association with the opening of the front face frame 60, and an angle between the first line part 74a and the second line part 74b and the helical axis 71 of the extensible helical part 72 can be larger. A force applied on the connection cable 70 in association with the opening of the front face frame 60 can be absorbed in an resiliency of the helical part to flexibly correspond to the opening of the front face frame 60, thereby serving to prevent the connection cable 70 from dropping off.
