摘要

A stator-vane structure that can suppress pressure loss caused by a gap or a level difference between liners, while forming an air channel with stator vanes made of a composite material and the liners in a turbofan engine, and the turbofan engine employing this stator-vane structure are provided. Inner liners (40) are made to butt against each other so as to clamp therebetween a vane base section (21) of a fan exit guide vane (stator vane) (20) made of a composite material, outer liners (50) are made to butt against each other so as to clamp therebetween a vane tip section (22) of the fan exit guide vane (20), respectively, and division lines (45, 46, 55, 56) that are formed between these liners on a leading-edge side are made to be along a streamline direction.
