点があつた。Conventional technology and problems to be solved In such compression coil springs, the coil diameter of the coil spring is regulated by the width of the spring receiving surface, and the wire diameter is regulated by the contact length. Previously, a large number of coil springs with small wire diameters and coil diameters were installed to obtain the desired load and deflection characteristics, but coil springs with small coil diameters had a small buckling load relative to their length. However, the device as a whole tends to tilt, and when a large number of coil springs are installed, it takes a long time to assemble the device, resulting in low work efficiency.

される効果を奏する。Structure and effects of the device As specifically explained in the above embodiments,
In the compression spring device of the present invention, two spring receivers each having an annular spring receiving surface of a constant width are placed opposite each other at a distance, and a spring wire is arranged in a substantially oval shape between the two spring receiving surfaces. The gist is that a plurality of helically wound compression coil springs are mounted with their major axis directed toward the circumferential direction of the spring receiving surface, and the radial cross-sectional shape of each compression coil spring is approximately oval. In addition to increasing the diameter of the coil, each compression coil spring was installed with its major axis facing the circumferential direction of the spring receiving surface.
The buckling load of each coil spring is large, making it difficult for the entire device to tilt, resulting in excellent stability.In addition, fewer compression coil springs are required to be installed between both spring receivers, reducing assembly time. It has the effect of being
