To provide an axle spring whose height can be adjusted without inserting a spacer between a flange part and a receiving part.SOLUTION: An axle spring comprises a shaft core 1, an outer cylinder 2, and an elastic layer 3 interposed between the shaft core 1 and the outer cylinder 2. The shaft core 1 comprises an upper shaft part 6 to which the elastic layer 3 is fixed, a flange part 7 formed under the upper shaft part 6, and a lower shaft part 8 connected to the flange part 7. The shaft core 1 has a structure that can be divided into an upper shaft core 1A including the upper shaft part 6 and a lower shaft core 1B including the flange part 7 and the lower shaft part 8. The height of the axle spring can be adjusted by inserting a spacer 17 between the upper shaft core 1A and the lower shaft core 1B.SELECTED DRAWING: Figure 4

    【課題】 フランジ部と受部との間にスペーサを挿入することなく、高さ調整が可能な軸ばねを提供することを目的とする。【解決手段】 軸芯1と、外筒2と、軸芯1及び外筒2の間に介装される弾性層3とを備え、軸芯1は、弾性層3が固着される軸上部6と、軸上部6の下方に形成されるフランジ部7と、フランジ部7に連設される軸下部8とを有する軸ばねであって、軸芯1は、軸上部6を含む上側軸芯1Aと、フランジ部7及び軸下部8を含む下側軸芯1Bとに分離可能な構成とし、上側軸芯1Aと下側軸芯1Bとの間にスペーサ17を挿入することにより軸ばねの高さ調整可能とする。【選択図】図4
