<P>PROBLEM TO BE SOLVED: To provide a Pachinko game machine capable of further improving a performance effect by a performance member which falls by gravity. Ž<P>SOLUTION: In the Pachinko game machine 1 which is provided with the performance member 12 that can be elevated and lowered at the prescribed position of a game board 4 and is capable of executing a performance by elevating and lowering the performance member 12 corresponding to game contents, the performance member 12 can fall by gravity while being rotated about a rotary shaft L extending in the vertical direction, and also includes a spiral shaft 13 which can be fitted to a projection 20c formed on the performance member 12 and has a groove 13a formed in a spiral shape and projected downwards so as to impart rotating force to the performance member 12 utilizing the gravity when the performance member 12 falls. Also, the distal end α of the spiral shaft 13 is formed narrower than other parts. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
