PROBLEM TO BE SOLVED: To provide a ventilator tower for a water storage tank capable of reliably performing ventilation in the water storage tank without being buried in the snow even in the case of a large amount of snowfall, and providing a favorable fine appearance without being conspicuous and adversely affecting a surrounding beautiful scene in the season of no snowfall. SOLUTION: The ventilator tower 10 is composed of a lower pipe 20 to be provided upright on a water storage tank 1 and fixed thereto, an upper pipe 30 whose lower side portion is fitted onto an upper side portion of the lower pipe 20 and whose upper portion is formed curvedly in a downward direction so that an upper side open end 31 thereof is disposed downwardly, and an insect screen 55 to be mounted on the upper side open end 31 of the upper pipe 30. The upper pipe 30 is formed in such a manner that it is vertically slidable along the lower pipe 20 in the direction in which the lower pipe 20 is provided upright and that it can be fixed to an arbitrary position where it is slided.
