あつた。Prior Art and Problems to be Solved by the Invention Conventionally, as a spring assembly in which a plurality of compression coil springs are mounted in a vertical position on one surface of an annular substrate of this type, Japanese Patent Publication No. 56-47419 discloses a substrate. A plurality of cylindrical protrusions are formed on one surface by burring at intervals in the circumferential direction, and a reduced diameter end turn formed at one end of a compression coil spring is fitted into the protrusions to form the protrusions. It is known that a compression coil spring is attached irremovably and freely compressible by caulking and expanding the upper end and pressing down on the end turn. When the protrusion is caulked, the end turn of the compression coil spring is compressed and plastically deformed, which adds harmful residual stress and reduces the strength.
Not only is it easy for the spring to break, but the crimped portion of the board may become distorted due to misalignment of the axes of the crimping tool and the protrusion, and the compression coil spring may be installed at an angle, making it difficult to assemble it with the mating member. There was a problem that prevented the smooth spring action of the compression coil spring.

る。 The present invention has been developed in view of the above-mentioned points, and there is no risk of plastic deformation occurring due to impact on the end-turn portion, which is the mounting portion, when a compression coil spring is attached to a board. It is an object of the present invention to provide a spring assembly that can be reliably attached to a substrate in a vertical position.

由に伸縮する効果を奏する。Structure and Effects of the Invention As specifically explained in the above embodiments,
A plurality of mounting bodies each having an outer circumferential surface as a guide part are vertically fixed to one surface of an annular substrate, a fitting groove is formed between the guide part and one surface, and each mounting body is provided with one end of the spiral winding part. A compression coil spring with a reduced diameter end turn part is
The helical winding part is fitted tightly into the guide part and the end winding part is fitted into the fitting groove, respectively, and the helical winding part is made to protrude from the guide part, and the compression coil spring is assembled to the mating member. The main feature is that a gap is created between the helical winding part and the guide part in the compressed state, and the compression coil spring is pushed in and the end winding part is inserted into the fitting groove of the mounting body. By fitting, each compression coil spring can be easily and securely attached to the board, and the end-turning part that is the mounting part will not be subjected to pressure and cause plastic deformation as if it were fixed by caulking. This not only prevents the strength of the end turn portion from decreasing and causing spring breakage, but also prevents the compression coil spring from tilting due to imbalance in the crimping force.
In addition, since a part of the spiral winding part is tightly fitted into the guide part in the free state, it can be reliably installed in a vertical position, and there is no space between the spiral winding part and the guide part in the compressed state. Therefore, after being attached to the mating member, it does not come into contact with the guide part and has the effect of freely expanding and contracting.
