PROBLEM TO BE SOLVED: To provide an attachment structure of a rigging part, in which the fatigue strength of a joint of the rigging part is particularly improved and the walls of a primary structural member are able to be made thin, and in which the time until cracks that occur at the joint spread to the primary structural member is drastically lengthened. SOLUTION: In an attachment structure of a rigging part 8 in which the rigging part 8 is attached to a brace 5 of a primary structural member which forms a semi-submersed structure, a doubling plate 10 continuously extending along in the axial direction of the brace 5 is fixed to the rigging part 8 and the doubling plate 10 is joined to the outside surface of the brace 5, such that the rigging part 8 is attached to the brace 5 via the doubling plate 10.
