PURPOSE:To improve the adhesion reliability of a web by burrying a fiber reinforced tape in the longitudinal direction of a web at a portion corresponding to the top face of the web to be adhered to the inside of a shell mold and a portion corresponding to the root section of web. CONSTITUTION:The shell of a blade 5 is constructed of a splitted shell mold 51 at the back (c) side and a shell mold 52 at the abdomen (d) side which are adhered respectively at the front edge (a) and the rear edge (b) through adhesives 10, 11. The abdomen side shell mold 52 has a web 53 formed by recessing the intermediate section in the traversing direction where the top face of said web 53 is adhered through an adhesive 12 to the inner face of the back side shell mold 51. A unilateral fiber reinforced tape 56 is burried along the longitudinal direction of the blade 5 at a portion corresponding to the top face of the web 53 and a portion corresponding to the root section of the web 53, thereby the reliability of adhesion between the shell molds 5, 52 and the web 53 is improved. |
