PROBLEM TO BE SOLVED: To provide a game machine capable of retaining smooth motions of a movable body for a long period of time. SOLUTION: A right movable presentation device 36 is disposed in such a way that a right movable body 39 can swing relative to a support member 38 mounted in a rear unit. The right movable body 39 has a movable base 41 disposed at one end in the longitudinal direction of an ornament body 40, and the movable base 41 is pivotally supported to the support member 38 swingably via a support shaft 46a. The support member 38 is composed of a mounting base body 43 and a cover body 44 opposed to each other in the longitudinal direction with the movable base 41 in-between. Rear spherical bodies 49 are disposed at regular intervals in the circumferential direction on the front surface of the mounting base body 43. The rear spherical bodies 49 are brought into contact with the rear surface of the movable base 41 in such a way as to freely roll. Front spherical bodies 63 are disposed at regular intervals in the circumferential direction on the front surface of the movable base 41. The front spherical bodies 63 are brought into contact with the rear surface of the cover body 44 in such a way as to freely roll. COPYRIGHT: (C)2011,JPO&INPIT |
