PROBLEM TO BE SOLVED: To provide a resin structure having a protruding reinforcing part drastically enhancing the cross-sectional secondary moment of a resin reinforcing part and extremely strong against bending deformation. SOLUTION: In a resin structure having a rib 20 integrally formed along with a resin structure 12 on the way of the resin structure 12 with predetermined thickness, a tensile force material 30 is embedded in the vicinity of the top part of the rib 20 along the longitudinal direction of the rib 20. As the tensile force material, fibers, yarns, steel, ropes or belts can be used. The resin structure 12 having the rib 20 is constituted of a polynorbornene resin obtained by a reactive injection molding method(RIM). |
