6. The structure of claim 5 , wherein after one end of the assembly bolt is engaged to the forward thread, the inner bolt is configured to move in the height direction along the reverse thread.
7. The structure of claim 1 , wherein the inner bolt allows for the step adjustment according to its amount of rotation.
8. A vehicle comprising:
a vehicle body including a vehicle floor panel;
a weld nut fixed to the vehicle floor panel;
an inner bolt positioned above and fixedly inserted into the weld nut; and
an assembly bolt inserted through the inner bolt and fastened to one end of the weld nut, wherein the inner bolt is configured to move in a height direction for step adjustment,
wherein the inner bolt comprises an inner bolt fastening part formed at an end of an inner bolt stopper,
wherein the inner bolt fastening part comprises a through-hole into which the assembly bolt is inserted,
wherein the inner bolt fastening part comprises a plurality of slits formed in the height direction and an inner protrusion formed at one end of the through-hole, and
wherein the assembly bolt is configured to push the inner protrusion outward while being inserted into the through-hole, and the inner bolt fastening part is configured to be expanded with respect to the slits to be compressed to the weld nut.
9. The vehicle of claim 8 , wherein the weld nut comprises:
a weld nut stopper exposed to an upper surface of the vehicle floor panel; and
a weld nut fastening part formed at an end of the weld nut stopper.
10. The vehicle of claim 9 , wherein the inner bolt comprises:
the inner bolt stopper formed above the weld nut stopper.
11. The vehicle of claim 10 , wherein:
a first end of the assembly bolt inserted through the through-hole is adjacent to the inner bolt stopper and a second end of the assembly bolt thereof is fastened to the weld nut.
12. The vehicle of claim 9 , wherein the weld nut fastening part comprises:
a reverse thread formed at its upper end for insertion of the inner bolt; and
a forward thread formed at its lower end for engagement with the assembly bolt.
13. The vehicle of claim 12 , wherein after one end of the assembly bolt is engaged to the forward thread, the inner bolt is configured to move in the height direction along the reverse thread.
14. The vehicle of claim 8 , wherein the inner bolt allows for the step adjustment according to its amount of rotation.
15. A fastening structure comprising:
a weld nut fixed to a vehicle panel, the weld nut comprising a weld nut stopper exposed to an upper surface of the vehicle panel and a weld nut fastening part formed at an end of the weld nut stopper;
an inner bolt positioned above and fixedly inserted into the weld nut; and
an assembly bolt inserted through the inner bolt and fastened to one end of the weld nut;
wherein the inner bolt is configured to move in a height direction for step adjustment; and
wherein the step adjustment is determined by an amount of rotation of the inner bolt,
wherein the inner bolt comprises an inner bolt fastening part formed at an end of an inner bolt stopper,
wherein the inner bolt fastening part comprises a through-hole into which the assembly bolt is inserted;
wherein one end of the assembly bolt inserted through the through-hole is adjacent to the inner bolt stopper, and the other end thereof is fastened to the weld nut;
wherein the inner bolt fastening part comprises at least two slits formed in the height direction and an inner protrusion formed at one end of the through-hole; and
wherein the assembly bolt is configured to push the inner protrusion outward while being inserted into the through-hole, and the inner bolt fastening part is configured to be expanded with respect to the slits to be compressed to the weld nut.
16. The fastening structure of claim 15 , wherein the inner bolt comprises:
the inner bolt stopper formed above the weld nut stopper.
