PROBLEM TO BE SOLVED: To solve such a problem that the spread of sound is small and the sound effect is poor because a sound transmission part is small and only one small sound transmission part is installed in a conventional game machine in which the outer periphery of a tray part of a ball tray device is covered by a ball tray cover member and the sound transmission part communicating with a sound source is installed on the cover member. SOLUTION: A game machine P has the cover member 5b with a depressed hollow back on the front side thereof, wherein the cover member 5b is formed with a plurality of sound transmission parts 10R, 10L disposed at different positions to communicate with the sound source 6 through a hollow space 9. In the game machine P, sound spreads widely since the plurality of sound transmission parts 10R, 10L communicating with the sound source 6 are formed at different positions on the cover member 5b.
