Claims

[Scope of utility model registration request]

A spring unit formed by connecting a large number of springs in a flat plate shape, an elastic material polymerized on at least one surface of the spring unit, and an exterior covering covered with a polymer of the elastic material and the spring unit. In the constructed pinerest, a plurality of single coil springs are disposed approximately at the center in the longitudinal direction of the spring unit, and a plurality of coil portions whose axes are approximately parallel are arranged at other portions, and adjacent A plurality of spring strips each having a substantially Z-shaped connecting rod that connects the upper and lower ends of the coil portion, respectively, are continuously formed by a single steel wire, and the spring strips extend in the longitudinal direction of the spring unit. A pine tress characterized by a substantially central portion that is formed to be more easily elastically deformed than other portions.
