PURPOSE:To reinforce a plate around the point where the stress is concentrated effectively by excavating a through hole for insertion of a center bolt in the thickness direction of the reinforcement body which is buried in the leaf spring. CONSTITUTION:A pair of reinforcements 2, 2 are about symmetrically installed at the central part in the longitudinal direction of the body 1 of a leaf spring, where a reinforcement 2 is composed of a column-like body 3 stretching deeper in the leaf spring and a flange 4 recessed from the surface of the leaf spring connected solidly with the end of said column-like body 3. A through hole 5 is excavated in the thickness direction of the leaf spring penetrating both the reinforcements 3, 3 and the leaf spring. |
