PURPOSE:To aim at reducing the steps of production and the number of required parts, by forming attaching sections to both ends of a coil spring as a cast integral structure. CONSTITUTION:An attaching parts 2, 3 are provided to both upper and lower ends of a material wire, and therefore they are integrally formed to obtain a coil spring. Screw holds 4 allow the attaching parts 2, 3 to be secured to the other member, and this spring may be used as both tension and compression spring. Accordingly, it is possible to reduce the steps of production and the number of required parts. |
