The present invention relates to a waterspout for preventing stain on a wall by being installed at a ventilation hole cap (10). The waterspout of the present invention comprises an inducing board (20) which is formed to be concave with a plurality of curvatures to the lower side of the ventilation hole cap (10) and is sloped to a vertical plane. The inducing board (20) becomes short towards both sides from a center part (25) and is extended to the left and right sides around a center line of the ventilation hole at an angle equal to or greater than 45°. Therefore, the ventilation hole waterspout of the present invention can minimize maintenance by applying by water stopping for rainwater without degrading the appearance of the ventilation hole cap having a small semi-spherical structure, and can keep an outer wall of a building clean. |
