PROBLEM TO BE SOLVED: To reduce the number of components and weight without reducing the function as a leaf spring. SOLUTION: In the leaf spring, a plurality of stacked leaves 1a-1n are fastened and fixed by inserting a center bolt 2 through the center of the leaves 1a-1n, and a blocked end of a U-bolt for mounting an axle is butted on and engaged with a central part on the upper surface of the leaves 1a-1n via a spring pad 3. A screw hole 3a corresponding to the center bolt 2 is disposed in the spring pad 3. A screw section 2a at the tip of the center bolt 2 inserted into the leaves 1a-1n from the opposite side of the spring pad 3 is screwed with the screw hole 3a, thereby effectively using the spring pad 3 conventionally having only a bearing surface forming function for the U-belt to fasten and fix the leaves 1a-1n.
