PROBLEM TO BE SOLVED: To provide a link structure which is lightweight and has a shape suitable for highly-rigid fiber-reinforced plastic. SOLUTION: In the link structure made of fiber-reinforced plastic having a joint section at least on an end of an arm section, the arm section has a face A facing to a plane parallel to the rotary center arranged on the joint section and a face B facing a plane perpendicular to the rotary center, and joint section has a face C facing the plane perpendicular to the rotary center and a flange face D rising at an angle against the face C. At least the face A and face D are connected with each other at one ridge line, and the face B and the face C are connected with each other in one ridge line. COPYRIGHT: (C)2009,JPO&INPIT
