PROBLEM TO BE SOLVED: To provide a pinball game machine capable of surely holding an elevating/lowering movable body in the initial position in the upper part of a performance display device by a simple structure. SOLUTION: A movable-gimmick device 23 includes: a base body 33 fixed inside a decoration case 22; a pair of rotary plates 36 having a slot 41; a motor 35 for rotatably driving both rotary plates 36 in both forward and backward directions; a pair of arms 38 in which a driving pin 43 installed on one end is freely slidably engaged with the slot 41; and a movable body 37 connected to the other end of both arms 38; wherein a pair of stopper protrusions 39 are installed in the base body 33. Then, the driving pin 43 is moved in the major axis direction inside the slot 41 accompanying the rotation of the rotary plates 36. Thereby avoiding contact between the arms 38 and the stopper protrusions 39 during the elevating/lowering operation of the movable body 37. Then, when the movable body 37 is in the initial position in the upper part, the arms 38 are brought into contact with the stopper protrusions 39, thereby preventing the movable body 37 from falling.
