PROBLEM TO BE SOLVED: To provide an axle spring for a vehicle with a simple damper not requiring an arrangement space for exclusive use while the increase of the number of parts and cost is reduced as much as possible by further devising the structure. SOLUTION: In the axle spring for the vehicle, an elastic part 3 having a laminated rubber structure where a plurality of elastic layers 4 and hard partition walls 5 are alternately laminated in the radial inward and outward direction in a concentric state with an axis P is interposed between a main shaft 1 and an outer cylinder 2 having the concentric axis P with each other. The axle spring is provided with a damper mechanism having a damper chamber 9 which can be expanded and contracted by a relative movement in the axis P direction of the main shaft 1 and the outer cylinder 2, and an orifice 12 communicated with the damper chamber 9. The damper chamber 9 is composed of a space part 7 enclosed by a closed part 6 for closing one end in the axial direction of the outer cylinder 2, the main shaft 2 and the elastic part 3.
