PURPOSE:To improve the strength of the eye section of an FRP spring by arranging the band-shaped or bar-shaped FRP spring made of FRP between a suspension link and a frame. CONSTITUTION:An FRP spring 10 id fitted to a frame 1, and its other end 10b is connected via a connection section 12 to the axle housing 6 of a suspension link 3 swayably supported by the frame 1 on one end 5. This connection section 12 connects the link 3 and the FRP spring 10 relatively movably in the longitudinal direction to each other. According to this constitution, when the link 3 is rotated upward around a shaft 5, the free end 10b of the FRP spring 10 is flexed upward accordingly. A wheel 7 is energized downward by its reaction force via the link 3. In this case, the longitudinal load is borne by the link 3, and only the vertical load is borne by the FRP spring 10. Therefore, the eye section of the FRP spring can be prevented from being damaged. |
