To appropriately provide a low-pitched sound to the front of a game machine frame.

A front panel 52 and a rear panel 53 are supported by a frame 51 while being separated in a back and forth direction to face each other, and a closed space surrounded by the frame 51, the front panel 52, and the rear panel 53 is constituted. The frame 51 is provided with a speaker installation part 60 and a frame sound outlet 65. The speaker installation part 60 is formed into a cylinder which is positioned outside the rear panel 53 and penetrates in the back and forth direction, wherein the frame sound outlet 65 opens to the front of the frame 51 at a position different from the speaker installation part 60. A low-pitched sound speaker 28 is installed to the speaker installation part 60 with its cone directed forward. When the front panel 52 is attached to the frame 51, an overhanging part 66 closes a front opening 62 and when the rear panel 53 is attached to the frame 51, an overhanging part 67 closes the rear part of the frame sound outlet 65.
