PURPOSE:To cause wearing for a low cost sliding seat, in such a case as to support one end of a leaf spring made of fiber reinforced plastic (FRP), without causing wearing for the expensive leaf spring made of FRP. CONSTITUTION:A sliding seat 2 is coated with its surface 2a by a material of Teflon, tellurin, high density molecule, etc. with small friction coefficient and large wear resistance further with less hardness than a leaf spring made of fiber reinforced plastic (FRP). Accordingly, the low cost sliding seat 2 is worn first, and an FRP leaf spring 1 can be extended its life. |
