<P>PROBLEM TO BE SOLVED: To provide a gutter for collecting game balls in a bank of Pachinko game machines, which is excellent in productivity, and capable of preventing a stop of game balls. Ž<P>SOLUTION: The gutter (25) constituting a groove-shaped passage forms a bottom wall with downward inclination at an prescribed angle θ from the upstream side toward the downstream side by continuously constructing a plurality of bottom panels (27) on both side walls (26). Either side wall (26) has a locked part (42) having downward inclination at an angle θ1, and each bottom panel (27) has a locking part (44) in which the difference in height H1 on the downstream side is larger than the difference in height H2 on the upstream side, and a flat part (43) having downward inclination at an angle θ2 relative to a reference line X of the locking part 44. With this structure, the flat part 43 forms the bottom wall of the gutter at the prescribed angle θ(θ1-θ2= θ) when the locking part (44) is locked to the locked part (42). When a plurality of bottom panels (27) are connected, a level difference (45) in which adjacent flat parts (43 and 43) descend from the upstream side to the downstream side is formed because of the structure that H1 is larger than H2.
