PROBLEM TO BE SOLVED: To provide an axle spring or the like capable of preventing settling of an axle spring in a simple structure and facilitating assembling and maintenance.
SOLUTION: Inner and outer sleeves 21 and 22 of the axle spring 20 are made of material having appropriate rigidity, strength, and durability. A coil spring 23 is disposed between both sleeves 21 and 22. A space on a lower plate 29 between both sleeves 21 and 22 is filled with a rubber made member 25. The rubber made member 25 has appropriate elasticity and damping property and is made of material having durability such as fatigue resistance and ozone resistance. The axle spring 20 is integrated as a component mounted to a bogie, so that the number of the components is reduced and lightening is realized, and labor for assembling and maintenance is not so required. Additionally, the coil spring 23 mainly loads a vertical load, so that vertical load is not charged on the rubber made member 25 and the settling of the axle spring 20 can be prevented.
