摘要:
This coil spring (1) has portions (1a, 1b) of high hardness and a portion (1c) in which hardness is lower than the portions (1a, 1b). It is also preferable that the hardness of portions (1a, 1b) that contact other parts is lower than the hardness of sections (1c) that are not said portions. Furthermore, it is preferable that the hardness of the end coil sections (1a, 1b) of the coil spring (1) is lower than the hardness of sections (1c) that are not said sections. And it is preferable that the hardness of the portions (1a, 1b) that contact receiving members (2, 3) for receiving the end coil sections of the coil spring (1) is lower than the hardness of sections (1c) that are not said portions.
摘要(中):
该螺旋弹簧(1)具有硬度高的部分(1a,1b)和硬度比部分(1a,1b)低的部分(1c)。 与其他部分接触的部分(1a,1b)的硬度最好低于不是所述部分的部分(1c)的硬度。 此外,螺旋弹簧(1)的端部线圈部分(1a,1b)的硬度优选低于不是所述部分的部分(1c)的硬度。 并且优选的是,与用于接收螺旋弹簧(1)的端部线圈部分的接收部件(2,3)接触的部分(1a,1b)的硬度低于不是(1c)的部分 所述部分。
