<P>PROBLEM TO BE SOLVED: To provide a game machine preventing falling of a movable object. <P>SOLUTION: The game machine includes: a movable object movably supported along a prescribed track with displacement in the vertical direction; a drive means for driving the movable object along the track in the X direction elevating in the vertical position; and a retaining means 33 for retaining the position of the movable object driven in the X direction. The movable object includes a body 13, and a driven body 15 mounted to the body 13 to be movable in parallel to the track within a prescribed range and driven by the drive means. The retaining means 33 includes: an engaging part 35 displaceably mounted on the body 13, abutting on the driven body 15, and displaced by the movement of the driven body 15 with respect to the body 13; and an engaged part 37 provided at the side of the body 13. The engaging part 35 and the engaged part 37 are configured to be engaged with each other and retain the position of the movable object when a relative position in the vertical direction of the driven body 15 to the body 13 is a prescribed upper limit position or higher, and not to be engaged with each other when the relative position is a prescribed lower limit position or lower. <P>COPYRIGHT: (C)2013,JPO&INPIT |
