Abstract
In a FRP leaf spring consisting of a main body and a rib, the main body has a taper portion so tapered that the thickness of the main body varies continuously along the longitudinal direction thereof, and the rib is projected integrally from the main body in the direction of the thickness thereof, extending along the longitudinal direction of the main body, so that the total sectional area of the main body and the rib, as well as the width of the main body, is kept substantially fixed in every position along the longitudinal direction to ensure uniform stress distribution.
