Description of the Related Art For example, in a bed mattress, a large number of coil springs are arranged in a matrix, and annular upper and lower receiving portions located at the upper and lower ends of the coil springs and adjacent to each other are connected in a rectangular plate shape by spiral wires. A frame is provided on the upper and lower peripheral edges to form a spring structure, and an elastic material such as urethane foam is polymerized on the upper and lower surfaces of the spring structure,
This polymer is formed by covering it with a bag-like exterior material.

を得られないということがある。In the spring structure having the above structure, the elastic material placed on the coil spring may easily fall off the upper and lower receiving portions because the upper and lower receiving portions of the coil spring are annular. Further load is applied to the receiving part first,
Since the load is received at a position far away from the axis of the coil portion, the load is applied to the coil portion not as a load along the axis but as an eccentric load, whereby a predetermined elasticity of the coil spring is provided. In some cases, the resilience cannot be fully utilized, so that the spring structure cannot obtain a predetermined cushioning property.

きる。According to the present invention, since the center of the connecting portion of the receiving portion projects near the axis of the coil portion, the projecting portion prevents the elastic material placed on the spring structure from falling off. Furthermore, since the load applied to the projecting portion of the receiving portion is applied near the axis of the coil portion of the spring, an eccentric load is also applied to the coil portion, but a load along the axis of the coil spring is also applied. Can be deformed along the axis, and can sufficiently exhibit the predetermined elasticity of the spring. Thereby, the spring structure can exhibit a predetermined cushioning property.
