A leaf spring L made of FRP (referred to as FRP) is laminated to form a leaf spring 1 for a vehicle, an interleaf 2 and a pad 3.
It is tightened and fixed to the axle 5 by U-bolts 4 via U-bolts 4, and a metal piece 6 with excellent wear resistance is attached as a silencer S between each leaf spring L so as to be in contact with each other. Figures 2 and 3
In the figure, at least one surface of the metal piece 6 is formed with unevenness, and the surface on which the unevenness is formed is brought into contact. Incidentally, the unevenness provided on the surface of the metal piece 6 in this way may be one in which a plurality of counterbore-shaped recesses 6a are provided on both surfaces of the metal piece as shown in the figure, and in reality, punched metal is used. It can also be used. Moreover, the unevenness may be trapezoidal. The material of the metal piece 6 is selected from, for example, a non-ferrous metal such as brass, or a material whose surface has been subjected to soft nitriding treatment such as tuftride.

のである。 The present invention is configured as described above, and its operation will be explained below. Each of the FRP leaf springs L is pressed against each other with a considerable force via a metal piece 6 serving as a silencer S, and while the vehicle is running, the leaf springs L are repeatedly moved in the longitudinal direction while being subjected to strong friction. In this case, since at least one surface of the metal pieces 6 is provided with unevenness, the coefficient of dynamic friction between the metal pieces 6 increases, and the dynamic spring constant of the leaf spring 1 itself also increases, and each leaf spring L made of FRP increases. One drawback of this is solved. Furthermore, due to the effect of the unevenness on the metal piece 6,
The damping capacity of each FRP leaf spring L has been improved, another drawback has been resolved, and since the FRP leaf springs L do not come into contact with each other, wear resistance has been improved, and the function as a leaf spring is also made of steel. It is something that will not lose its color.
