Description

  The present invention relates to a coupling structure that couples a first coupling target and a second coupling target.

  As a coupling structure, the collar and another member are sandwiched between the bolt and the nut by screwing the nut into a bolt that is penetrated by the collar mounted in the bolt hole of the resin member and another member. Then, there is one in which a resin member and another member are combined (see, for example, Patent Document 1).

However, in this coupling structure, the holding force of the resin member collar due to the collar depends on the mounting force of the collar on the bolt hole of the resin member, so it is difficult to adjust the holding force of the resin member collar due to the collar. It is.

  The coupling structure 10 according to the present embodiment includes a flat plate-like FRP 12 (Fiber / Reinforced / Plastic, fiber reinforced plastic) as a first coupling target. The FRP 12 has a columnar first through hole 14. It is formed through.

  A metal substantially cylindrical collar 16 as a first locking member is passed through the first through hole 14, and the inside of the collar 16 is a columnar insertion hole 18. At one end of the collar 16, a substantially polygonal flat plate-shaped flange portion 16 </ b> A as a first locking portion is integrally formed, and the flange portion 16 </ b> A is locked to one side surface 12 </ b> A of the FRP 12. A metal substantially polygonal flat plate-shaped fixing ring 20 as a first clamping member is screwed to the other end of the collar 16, and the fixing ring 20 presses the other side surface 12 </ b> B of the FRP 12. The FRP 12 is sandwiched between the flange portion 16 </ b> A and the fixing ring 20.

  A metal bolt 22 as a second locking member is passed through the FRP 12 through the first through hole 14 in a state of being inserted through the collar 16 through the insertion hole 18. A substantially polygonal columnar head portion 22 </ b> A as a second locking portion is integrally formed at one end of the bolt 22, and the head portion 22 </ b> A is locked to the collar portion 16 </ b> A of the collar 16.

  On the other side of the FRP 12, a metal plate-like assembly component 24 as a second coupling target is arranged. The assembly component 24 is a fastening that is generated by screwing the bolt 22 and the nut 28 unlike the FRP 12. It is made of a material having high deformation strength that does not sag against force (fastening axial force, coupling force). A cylindrical second through-hole 26 is formed through the assembly component 24, and the other end of the collar 16 (indentation) is formed on one side 24 </ b> A of the assembly component 24 around the entire circumference of the second through-hole 26. The end of the portion 16A is locked.

  The assembly part 24 is penetrated by the bolt 22 through the second through hole 26. A metal substantially polygonal columnar nut 28 serving as a second clamping member is screwed to the other end of the bolt 22 (on the side opposite to the head 22A), and the nut 28 attaches to the other side 24B of the assembly component 24. By pressing, the collar 16 and the assembly component 24 are sandwiched between the head portion 22 </ b> A of the bolt 22 and the nut 28, and the FRP 12 is coupled (fastened) to the assembly component 24.

The FRP 12 is coupled to the assembly component 24 in a state in which rattling between the collar 16, the fixing ring 20, the assembly component 24, the bolt 22, and the nut 28 of the FRP 12 is eliminated by being sandwiched between them.

  Here, the fastening force (clamping force) of the collar 16 and the assembly component 24 by the bolt 22 and the nut 28 is not input to the FRP 12 having a low deformation strength. For this reason, the collar 16 and the assembly component 24 can be fastened with high axial force by the bolt 22 and the nut 28, the FRP 12 can be firmly coupled to the assembly component 24, and the nut 28 is screwed onto the bolt 22.
