PROBLEM TO BE SOLVED: To provide a game machine that includes movable performing means and can suppress malfunctions caused by enhancement of attention degree to a game while suitably performing the enhancement.SOLUTION: A third movable performance device includes: a center decoration body that is provided at a standby position/performance position in a manner capable of being displaced and rotates in a prescribed direction at the performance position; an arm part that is provided rotatably and holds the center decoration body; a drive motor for rotation that generates drive power to rotate the center decoration body; and multiple transmission gears 383 that transmit the drive power from the drive motor for rotation to the center decoration body. With respect to a fixed gear 384 and a specific movable gear 386 constituting each of the transmission gears 383, the former is arranged at a rotation center part of the arm part and the latter is arranged at a position distant from the rotation center part. Backlash in rotating the center decoration body is reduced when the specific movable gear 386 rotates after moving along an outer periphery of the fixed gear 384 in association with the displacement of the center decoration body from the standby position to the performance position. |
