PROBLEM TO BE SOLVED: To provide a rotor hub structure of a rotor craft for reducing the weight and improving the reliability thereof by simplifying the structure. SOLUTION: Since an elastomeric bearing 130 is disposed on an inner side in the radial direction of an arm part 83 formed in a loop which is substantially U-shaped inwardly in the radial direction out of a frame body 82, the elastomeric bearing 130 is pressed against the arm part 83 by a large centrifugal force applied to a yoke 18. The centrifugal force and the shear force can be transmitted by this structure, and a load transmission structure is simplified compared with a conventional structure disclosed in the official gazette.
