PURPOSE: A suspension for a vehicle is provided to improve the rectilinearity and the travel stability, and to drive safely by preventing deviation during traveling with adjusting the wheelbase according to rotation of a spring pin. CONSTITUTION: An end of a leaf spring(1) surrounds a spring bush(16), and overlaps with a spring pin bracket(3) installed in a side frame. A spring pin(2) penetrates the spring pin bracket and the spring bush, and combines a spring pin nut(17) by a screw. The end of the leaf spring is combined with the spring bracket by the spring pin. Screw grooves(2a,16a) are formed in the outer periphery of the spring pin and the inner periphery of the spring bush to assemble the spring pin and the spring bush. The pitch of the screw groove of the spring pin is deviated to the center of the pin, and the wheelbase is adjusted according to rotation of the spring pin.
