Abstract
A spout nozzle for a scum removal device provided in water where scum floats: a tip-end-side nozzle part of a nozzle body is formed in a flat cylindrical shape; a valve body closing a discharging opening by its own weight when pressure water is not supplied is provided in the tip-end-side nozzle part; a closing part closing an opening above the discharging opening when the discharging opening is closed is provided on the valve body; therefore, resistance is small even if it is arranged in water and moreover an interior is hardly stained by scum and the like contained in water.
