PROBLEM TO BE SOLVED: To provide an improved vehicular axle spring capable of providing a nonlinear characteristic capable of exhibiting excellent ride comfort and the swinging reducing action, regardless of a change in variously changing sprung weight, while being put in a superior state even in durability, without risk of noise and early abrasion, without increasing the number of parts. SOLUTION: This vehicular axle spring is formed by interposing an elastic part 3 of a laminated rubber structure of alternately laminating a plurality of elastic layers 4 and a hard partition wall 5 in the radial inner-outer direction in a state of being concentric or substantially concentric with the axis P between a main shaft 1 and an outer cylinder 2 having mutually the same or the substantially same axis P with this main shaft, and is equipped with a fluid suspension mechanism (b) having a sealed chamber 7 expanded-contracted by the relative movement in the axis P direction of the main shaft 1 and the outer cylinder 2 and filled with suspension fluid 8.
