<p><P>PROBLEM TO BE SOLVED: To solve problems in blades for a conventional fan, wherein it is troublesome to clean oil smudge, and although there is a method of making the blades of paper and replacing them when soiled, these blades are formed in a solid shape in a manufacturing stage, and are deformed, damaged, or the like during transportation unless they are packed or wrapped to a certain extent. <P>SOLUTION: The blade whose contour is cut out of a paper plate 1, is sold as it is in plate shape, and a consumer who purchased the blade bends the root part of the blade 3 when mounting it to the ventilating fan to form the blade 3 three-dimensionally, thus providing the paper-made blade for the ventilating fan that can be circulated even in simple wrapping, and its mounting method is also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
