摘要：PROBLEM TO BE SOLVED: To provide a flap hinge mechanism, its manufacturing method and a flap hinge device realizing smooth flap action against strong centrifugal force and reducing thickness and weight. SOLUTION: A flap hinge mechanism 10 consists of a blade fixing part 11 fixed on a blade 1, a flap fixing part 12 fixed on a flap 2 and a joint part 13 jointing the blade fixing part 11 and the flap fixing part 12 flexibly in angular location. The blade fixing part 11, the joint part 13 and the flap fixing part 12 are made of composite material fibers. Matrixes are impregnated into the fibers of the blade fixing part 11 and the flap fixing part 12 but are not impregnated into the fibers of the joint part 13.
