PURPOSE: To achieve higher assembling performance while curtailing the number of parts by arranging a mobile bottom plate and an engaging lever to be loaded on or unloaded from a curved rail in the final position of the assembling of the curved rail built by assembling a plurality of ball passages provided with partition walls and a ball vacancy detector sequentially. ;CONSTITUTION: In a curved rail 5 to lead prize balls in a prize ball tank arranged on the rear surface of a game board to a prize ball releasing device, pivot parts 17 and 29 are provided at a bend part of a mobile bottom plate 15 and the end of the rotation of an engaging lever 16 and small-diameter shafts 18, 19, 30 and 31 are provided protrudingly at both side ends of the pivot shaft parts 17 and 29. On the other hand, bearings 23 and 34 for supporting the small-diameter shafts 19 and 31 are provided on an outer plate 7 at a hole rim on the upstream side of a ball withdrawing hole 20 and at a lower part thereof. U-shaped cuts 25 and 36 are made on the outer circumferences of the bearings 23 and 34 to elastically function the bearings 23 and 34. A rear plate 9 is provided with shaft holes 26 and 37 at positions facing the bearings 23 and 34 to mount the small-diameter shafts 18 and 30.;COPYRIGHT: (C)1996,JPO
