FASTENING STRUCTURE OF FIBER-REINFORCED RESIN FRAME

摘要

PROBLEM TO BE SOLVED: To provide a fastening structure of a fiber-reinforced resin frame which can reduce a weight and a size of the fiber-reinforced resin frame.SOLUTION: A fiber-reinforced resin frame 50 includes a first member 51, and a second member 52 laminated and adhered to the first member 51. The first member 51 is arranged between another frame 14 and the second member 52, and includes a first through hole 61 penetrating in a thickness direction. A collar member 70 is fitted to the first through hole 61. The first through hole 61 and an outer circumference surface 71 of the collar member 70 are adhered. The second member 52 includes a second through hole 62 which penetrates in the thickness direction and has a smaller diameter than the first through hole 61. One end surface 73 of the collar member 70 directly abuts on an inner surface 52b around the second through hole 62 of the second member 52. A bolt 40 penetrates the second through hole 62 and a hollow part 72 formed on the collar member 70 to fasten the fiber-reinforced resin frame 50 to the other frame 14.
