When the swing arm 131 is swung downward with the game board 101 tilted backward, the placement surface is placed on the surface on which the game board 101 is placed (the lower end of the decorative board 52 abuts). The support part 133 comes into contact.

  As in the ball gathering cover 10 of the first embodiment, an arm housing portion 116 is formed from the left and right side portions of the ball gathering cover 110 to the upper end (according to the shape of the swinging arm 131). By swinging the movable arm 131 upward, the swing arm 131 is accommodated in the arm accommodating portion 116. Further, when the swing arm 131 is swung (upward) to the arm accommodating portion 116 (upward), the placement surface support portion 133 is engaged with the engagement member 117 formed on the upper part of the ball-shifting cover 110 (or the decorative plate 52). The swing arm 131 is fixedly held by the arm accommodating portion 116.

  In order to make the gaming board 101 self-supporting using the tilt prevention mechanism 130 of the gaming board 101 configured as described above, first, the swinging arm 131 housed in the arm housing portion 116 is swung downward to swing. The cover engagement portion 132 of the arm 131 is engaged with the first engagement hole 113 or the second engagement hole 114 of the attachment hole 112.

  At this time, for example, the cover engagement portion 132 is positioned behind the first engagement hole 113, and the engagement surfaces 132 a and 132 a of the cover engagement portion 132 are connected to the upper and lower bottom surfaces of the first engagement hole 113. The swing arm 131 is swung so as to be parallel, and in this state, the swing arm 131 (cover engaging portion 132) is moved forward in parallel. Then, each engagement surface 132a, 132a contacts the upper and lower bottom surfaces of the first engagement hole portion 113, the cover engagement portion 132 engages with the first engagement hole portion 113, and the swing arm 131 moves to the decorative plate 52. Is held in a state inclined by a predetermined angle (that is, the swing of the swing arm 131 is restricted).

  Further, for example, the cover engagement portion 132 is positioned behind the second engagement hole portion 114, and the engagement surfaces 132 a and 132 a of the cover engagement portion 132 are parallel to the upper and lower bottom surfaces of the first engagement hole portion 114. The swing arm 131 is swung so that the swing arm 131 (the cover engaging portion 132) is moved forward in this state. Then, each engagement surface 132a, 132a contacts the upper and lower bottom surfaces of the second engagement hole portion 114, the cover engagement portion 132 engages with the second engagement hole portion 114, and the swing arm 131 moves to the decorative plate 52. Is held in a state inclined by a predetermined angle (that is, the swing of the swing arm 131 is restricted).

  In this way, the game board 101 is placed on a predetermined surface in a state where the swing arm 131 is inclined at a predetermined angle with respect to the decorative plate 52 and the swing of the swing arm 131 is restricted (the decorative plate 52). The lower surface of the game board 101 is brought into contact with the surface on which the game board 101 is placed, and the placement surface support portion 133 of the swing arm 131 is brought into contact with the surface on which the game board 101 is placed. The game board 101 is made independent by supporting the side. Thereby, the game board 101 can be made independent easily.

  Further, when the cover engagement portion 132 is engaged with the second engagement hole portion 114, the relative height of the placement surface support portion 133 (with respect to the decorative plate 52) is the same as that of the first engagement hole portion 113. Since it becomes higher than when engaged, the inclination angle of the game board 101 when the swing arm 131 supports the back side of the game board 101 becomes larger than when engaged with the first engagement hole 113. Thereby, the inclination angle at the time of making the game board 101 become independent changes as needed by changing the engagement position (the first engagement hole 113 or the second engagement hole 114) of the cover engagement part 132. Can be made.

  In order to house the swing arm 131 in the arm housing portion 116, the swing arm 131 is translated backward to release the engagement state between the cover engagement portion 132 and the engagement hole portions 113 and 114. Thereafter, the swing arm 131 may be swung upward and housed in the arm housing portion 116. At this time, the mounting surface support portion 133 of the swing arm 131 is engaged with the engagement member 117, and the swing arm 131 is fixedly held by the arm housing portion 116.
