PROBLEM TO BE SOLVED: To solve a problem of static electricity affecting electronic components of game machines in the conventional art which inevitably allows the generation thereof in balls flowing through the ball gutter, while the static electricity generated once is hard to be released. SOLUTION: In the ball gutter, for example, a vertical case 1 of the cylindrical ball gutter is built up of a conducting material and a through hole 20 is provided at a part of the circumferential surface of the cylinder of the vertical case 1 of the cylindrical ball gutter piercing the inside thereof and an electroconductive part provided on the body side (mechanism plate 13) is so positioned as to contact balls flowing through the ball gutter 1A by way of the through hole 20. Otherwise, a holding means (holder 40) is provided to hold and mount the vertical case 1 of the cylindrical ball gutter on the body side of the game machine while the through hole 20 is provided at a part of the circumferential surface of the cylinder of the vertical case 1 of the ball gutter piercing the inside thereof. An electroconductive part of the holding means is so positioned as to contact balls flowing through the ball gutter 1A by way of the through hole 20. COPYRIGHT: (C)2003,JPO
