PROBLEM TO BE SOLVED: To solve problems in a conventional stirring fan of dripping of water droplets from a tip of a nozzle onto crops from an upper part of a house when water supply to a nozzle is stopped, the water droplets giving shock to the crops with buds in an actual house as the droplets give considerable shock to the crops, and further the droplets giving shock to leaves, causing damage and disease of the leaves. SOLUTION: This nozzle structure of the agricultural stirring fan is composed of an air duct comprising a suction side and a discharge side, a stator vane mounted on a converging discharge-side inner part of the air duct, a porous body mounted on a center of the stator vane, a bellmouth mounted on the air duct, a stirring fan blade mounted on a front part of the bellmouth, a guard for protecting the stirring fan blade, a frame body connecting the guard and the air duct over the bellmouth, and a motor mounted on the frame body for rotating the stirring fan blade.
