Abstract

PURPOSE:To prevent the strength of a leaf spring of fiber-reinforced plastic from falling due to the presence of a through hole, by embedding reinforcing plates in the body of the leaf spring, making the reinforcing plates of fiber-reinforcing plastic and providing the plates with through holes which extend in the dirction of the thickness and are concentric with that of the leaf spring. CONSTITUTION:A pair of reinforcing members 2, 2 are provided in the longitudinally middle part of the body 1 of a leaf spring made of fiber-reinforced plastic. Each reinforcing member 2 is made of a plate of fiber-reinforced plastic and has a through hole 3 extending in the direction of the thickness and is integrally embedded in the leaf spring body 1 near its surface. The leaf spring body 1 has a through hole 4 almost concentric with the through hole 3 and having the same diameter as the latter. Since the leaf spring body 1 and the reinforcing members 2 are almot equal in the strain characteristic, lastic modulus, etc. and equal in bonding properties, cracks or the like do not occur around the through hole 4.
