PROBLEM TO BE SOLVED: To prevent an ornament that performs direction effects characteristic in progressing a game by appearing to a front surface of a game board of a Pachinko game machine or the like from tilting either toward the left or the right and moving, being unable to maintain a regular rising attitude due to backlash between gears for transmitting driving force to the decorative body.SOLUTION: An ornament jack-up device includes: a pair of right and left turning arms 40, 41 having elongated holes 40A, 41A whose one end parts are pivoted turnably in the vertical direction by bearing support members 35 supported by base members 32 and are formed through side surfaces nearer the other ends; the ornament 50 guided so that it fixes a movable shaft 55 loosely fitted into the elongated holes to a lower part and rises/lowers as the turning arms rotate; an intermediate shaft 60 integrally linked between the respective turning arms; and a driving mechanism 70. The driving mechanism includes: a driven gear whose axis center part is turnably supported by an end part of the bearing member; a driving gear engaged with the driven gear; and a motor for driving the driving gear. |
