PROBLEM TO BE SOLVED: To solve the problem of a conventional fan for agriculture and livestock industries, generally composed of a frame for a bellmouth, a drum or the like, a vane wheel driven by a motor and a guard, which are integrally formed with the tip ends of vanes arranged very closely to the frame, that they require accuracy/skill for forming, assembling or the like so that it is difficult to assemble them on site because they are designed to be assembled at factory and shipped therefrom by trucks or the like.;SOLUTION: The fan for agriculture and livestock industries is composed of a frame, supports to be fixed thereto, a driving part provided on the supports and a vane wheel supported by the driving part with a bearing. Each support is composed of a base portion, bent intermediate portions extending therefrom and a supporting tip end provided at the tip ends of the bent intermediate portions. The base portion is fixed to the frame and the supporting tip end is fixed to the casing of the driving part. Accordingly, the vane wheel does not need centering so that they can be shipped as parts to be assembled on site. In addition, it is possible to provide a ventilating fan reduced in hydraulic resistance and of a robust tubular structure.;COPYRIGHT: (C)2004,JPO&NCIPI
