<P>PROBLEM TO BE SOLVED: To provide a movable accessory (yakumono) device of a game machine that can be constituted compactly. <P>SOLUTION: The movable accessory device of a game machine includes: an action shaft 130 erected in an actuation gear 120; a first plate 140 that can be rotated around a rotary shaft 150 and includes a first groove 141 where the action shaft 130 is inserted; and a second plate 170 that is provided slidably to the first plate 140 and includes a second groove 171 where the action shaft 130 is inserted. The first groove 141 includes: a first groove part 141a formed linearly; and a curved groove part 141b formed along a rotation locus L drawn by the action shaft 130. The second groove 171 includes: a second groove part 171a formed in the same shape as that of the first groove part 141a; and a sliding groove part 171b formed such that the radius of curvature of the connection part to the second groove part 171a is smaller than the radius of curvature of the connection part to the first groove part 141a of the curved groove part 141b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
