The tip of the return ball prevention valve 120 only needs to be in contact with or close to the inner surface of the outer band 116 located on the game area 112 side. The degree of contact is such that there is a gap smaller than the diameter of one sphere between the tip of the return ball prevention valve 120 and the inner surface of the outer band 116, and along the inner surface of the outer band 116 from the game area 112. Thus, it is only necessary that the sphere that goes back to the launching passage 115 does not get caught between the tip of the return ball prevention valve 120 and the inner side surface of the outer band 116 without passing.

  Then, the ball fired from the launch mechanism 105 pushes the return ball prevention valve 120 from the launch passage 115 and opens the return ball prevention valve 120 so that the tip of the return ball prevention valve 120 is separated from the outer band 116. The return ball prevention valve 120 is elastically deformed toward the game area 112 as a whole with reference to the attachment portion. Then, the ball that pushes open the return ball prevention valve 120 moves away from the return ball prevention valve 120 toward the game area 112, so that the tip of the return ball prevention valve 120 approaches the outer band 116. The prevention valve 120 is restored to the form shown in FIG. 3 as a whole. Thus, in the restored form of the return ball prevention valve 120, when a ball launched from the launch passage 115 to the game area 112 moves backward from the game area 112 toward the launch path 115, the ball is returned to the return ball. The collision with the prevention valve 120 prevents the return ball prevention valve 120 from being taken into the launch passage 115 from the game area 112 and bounces back to the game area 112.

The game board 110 is pushed rearward, and the game board 110 is rotated backward with the left side sandwiched between the game main body receiving part 98 and the game main body pressing part 97 as the center of rotation. When stored in the game main body storage chamber 95, the lower surfaces 143 of the left and right protrusions 141 having a smaller area than the lower surface 142 of the game board 110 come into contact with the upper surface of the game main body shelf 103, so that the game board 110 is entirely There is an advantage that the game board 110 can be stored in the game main body storage chamber 95 with a small pressing force as compared with the case where the lower surface 142 of the game board 110 is rotated to the rear side and the entire lower surface 142 of the game board 110 contacts the upper surface of the game main body shelf 103. is there. Since the slope 146 is located on the front side where the game board 110 is pushed in the direction of the game main body storage chamber 95 with respect to the protrusion 141, the game board 110 is formed by the game main body receiving portion 98 and the game main body pressing portion 97 from the front and rear direction. The inclined surface 146 is guided to rise to the game main shelf 103 of the game board 110 as it is rotated rearward with the sandwiched left side as the rotation center, and the lower surfaces 143 of the left and right protrusions 141 are moved with a small pressing force. There is an advantage that it can be mounted in contact with the upper surface of the game main shelf 103.

  Since the left and right protrusions 141 have the same height from the lower surface 142 of the peripheral ornament structure 111, when the lower surfaces 143 of the left and right protrusions 141 are mounted in contact with the upper surface of the game main shelf 103, The lower surface 142 is parallel to the upper surface of the game main shelf 103. Accordingly, the game components such as the center ornament 131, the general prize component 132, the operation prize component 133, the start prize component 134, the variable prize component 135, and the game nail 136 are horizontally placed on the game board 110 with respect to the lower surface 142 of the game board 110. By being attached, when the game board 110 is mounted in the game main body storage chamber 95, there is an advantage that each game component is in a parallel state. When the movable frame 75 is attached to the fixed frame 72, the upper surface of the game main shelf 103 is parallel to the lower surface 72a of the fixed frame 72, and the lower surface 72a of the fixed frame 72 to which the movable frame 75 is attached is not shown in the figure. When the fixed frame 72 is attached to the game installation structure in contact with the horizontally formed mounting upper surface for installing the game machine of the installation structure, the upper surface of the game main shelf 103 becomes a horizontal plane. Therefore, when the gaming machine frame 71 is attached to the gaming installation structure and the gaming board 110 is mounted on the gaming machine frame 71, each gaming component is in a parallel state, so that the gaming area 112 flows down from the top to the bottom. The flow of balls is uniform, and there is no bias in ball winning with respect to each of the general winning component 132, the operating winning component 133, the starting winning component 134, and the variable winning component 135, and it is possible to improve quality reliability. There is.
