To provide an axle spring which is easily assembled and capable of suppressing an assembly defect while comprising a directional mounting plate.SOLUTION: The present invention relates to an axle spring 1 comprising: a main axle 2 and an outer cylinder 3; an elastic part 4 interposed therebetween; a mounting plate 9 which is fitted to an upper end opening of the outer cylinder 3; a regulation mechanism 16 with which a main axle side member 2a and a mounting plate side member 17 are brought into contact and which regulates relative displacement of the main axle 2 and the outer cylinder 3 in a horizontal direction; and multiple fixing parts 15 formed in the outer cylinder 3 and each including a screwing hole 14. The regulation mechanism 16 is provided in such a manner that a distance from the main axle side member 2a to the mounting plate side member 17 becomes different in a longitudinal direction X and a lateral direction Y. The multiple fixing parts 15 are properly screwed to a vehicle 30 only in a case where longitudinal and lateral directions of the vehicle 30 and the axle spring 1 are matched. The mounting plate 9 includes a flange part 13 covering the screwing holes 14, and a through-hole 19 is formed in the portion of the flange part 13 which is overlapped with the multiple screwing holes 14 in a state where the mounting plate 9 and the outer cylinder 3 are fitted while matching the longitudinal and lateral directions.SELECTED DRAWING: Figure 2

    【課題】方向性を有する取付板を備えつつ、組立が容易で、組立不良を抑制可能な軸ばねを提供する。【解決手段】主軸2及び外筒3と、その間に介装される弾性部4と、外筒3の上端開口部に嵌合される取付板9と、主軸側部材2aと、取付板側部材17とが接触して主軸2及び外筒3の水平方向の相対的変位を規制する規制機構16と、外筒3に複数形成された、ネジ止め孔14を有する固定部15とを備えた軸ばね1であって、規制機構16は、主軸側部材2aから取付板側部材17までの距離が前後方向Xと左右方向Yとで異なるように設けられ、複数の固定部15は、車両30と軸ばね1の前後左右方向が一致するときのみ、車両30に適正にネジ止め可能とされ、取付板9は、ネジ止め孔14を覆うフランジ部13を有し、取付板9と外筒3とを前後左右方向を合せて嵌合した状態で、複数のネジ止め孔14と重なるフランジ部13部分に貫通孔19が形成された構成とする。【選択図】図2
