The present invention relates to a nut apparatus for fastening a U-bolt. When a glass fiber composite material spring (4) is shrunk and thickness (volume) is reduced as an ambient temperature becomes low in a rear-wheel biaxial suspension device provided with the glass fiber composite spring (4) and a steel-made U-bolt (10), conversely, liquid (22a) contained in a fluid bag (22) in a nut device (20) fastened to the U-bolt (10) is phase-changed to a solid (22b). As a result, the volume (thickness) of the fluid bag (22) expands, and consequently, a phenomenon of reduction of axial force of the U-bolt (10) can be prevented by using the expanded fluid bag (22).

    본 발명은 유볼트 체결용 너트장치에 관한 것으로, 유리섬유 복합재 스프링(4)과 스틸 재질의 유볼트(10)가 함께 구비된 후륜 2축 현가장치에서 대기온도가 저온상태가 됨에 따라 복합재 스프링(4)이 수축되어서 두께(부피)가 줄어드는 경우, 반대로 유볼트(10)와 체결된 너트장치(20)에서 유체주머니(22)에 담겨진 액체(22a)가 고체(22b)로 상변화되고, 이로 인해서 유체주머니(22)의 부피(두께)가 팽창하며, 팽창된 유체주머니(22)를 이용해서 결과적으로 유볼트(10)의 축력감소 현상을 예방할 수 있도록 된 것이다.
