<P>PROBLEM TO BE SOLVED: To achieve easy processing and cost reduction, to obtain a strength necessary for a supporting member and to achieve stable conveying. Ž<P>SOLUTION: A physical lottery device includes: a rails 47a and 47b for preventing dropping which support a lottery ball 73 from below and which are formed so that at least supporting surfaces are partially formed of vertically curved surfaces; and structure for regulating lateral movement of the lottery ball. The lateral movement of the lottery ball is regulated by contacting the lottery ball from a lateral direction orthogonal to a conveying direction while the lottery ball is conveyed by rolling or sliding on the rails for preventing dropping by being pushed from the rear of the conveying direction. The rails for preventing dropping support the lottery ball from below by end faces of a plurality of plate members arranged by separating each other. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
