Claims

[Scope of utility model registration request]

In a coil spring that is wound into a coil and has hook parts formed at both ends, both wire rods (hereinafter referred to as two parts) formed by bending one wire rod at the middle part thereof are brought into contact with each other in parallel from the bent base. A hook part 2 shared by the two parts is formed at the bent side end of the linear body, and the linear body is connected to the hook part 2 to form a spring body. A coil spring which is wound into a coil shape and further includes a dedicated hook portion 3 formed at the other end of the two portions, that is, at both ends of the single wire.
