PROBLEM TO BE SOLVED: To provide a Pachinko game machine which can prevent a trouble due to contact of a movable part in an accessory device. SOLUTION: A rib 46 is formed unitedly on the rear side of a rear side cover 42. The rib 46 is made along the swinging direction of a swinging accessory device and when the swinging accessory device gets into contact with a turning device, the rib 46 makes a contact with the turning device. In addition, the rib 46 is made so that its cross-section in the roughly perpendicular direction to the swinging direction is roughly semi-circular whose center is protruding. Furthermore, the rib 46 is made so that the center part in the swinging direction is highest and the height gradually decreases toward both ends in the swinging direction. With this constitution, the force applied when the swinging accessory device makes a contact with the rotation accessory device is deviated away from the swinging direction, and, therefore, the problem that the swinging accessory device is stopped or broken due to contact is prevented.
