Abstract

A lower-side spring receiving member is adapted to receive a compression spring provided with an effective part, end turn parts which do not elastically deform, and rising parts located between the effective part and the end turn parts, at a lower side of the compression spring. The lower-side spring receiving member is provided with a contact part which is formed to protrude outward from an end at one side in the extending direction thereof, and which is in contact with the rising part so as not to form a gap between the contact part and the rising part. The contact part is in contact with the rising part of the compression spring by an elastic force caused by elastic deformation, regardless of a load on the compression spring.

First claim

The invention claimed is:

1. A lower-side spring receiving member adapted to receive a compression spring at a lower side of the compression spring, the compression spring having an effective part, first and second end turn parts which do not elastically deform, and first and second rising parts located between the effective part and the first and second end turn parts, respectively, the lower-side spring receiving member comprising:
a contact part that is formed to protrude outward from one end in an extending direction of the lower-side spring receiving member, and adapted to be in contact with the first rising part so as not to form a gap between the contact part and the first rising part, and the contact part is in contact with the first rising part by elastic force caused by elastic deformation of the compression spring, regardless of a load on the compression spring;
a load receiving part adapted to receive a spring load of the compression spring, the load receiving part being formed on an opposite side of the contact part at the one end in the extending direction of the lower-side spring receiving member, and formed to protrude outward farther in a winding direction of the compression spring than a tip of the contact part when viewed in an axial direction of the compression spring, and to swell outward with a convex curvature; and
a sloping part adapted to receive the first rising part, a width of the sloping part viewed in the winding direction of the compression spring gradually becoming greater as the sloping part becomes distant from the first end turn part connected to the first rising part.

2. The lower-side spring receiving member according to claim 1 , further comprising
an expansible deformation part that is provided between the contact part at the one end and the load receiving part, and adapted to elastically deform depending on a load on the compression spring, wherein
the expansible deformation part has a thinner shape than the load receiving part.

3. The lower-side spring receiving member according to claim 1 , wherein
the sloping part is formed to extend from a flat part and has a thickness gradually increasing along the first rising part.

4. The lower-side spring receiving member according to claim 1 , wherein
the contact part is adapted to be in contact with or abut on nearly the same location on the first rising part in deformation of the first rising part.

5. The lower-side spring receiving member according to claim 1 , wherein
an upper-side spring receiving member located on the other side of the compression spring, which is adapted to receive the compression spring together with the lower-side spring receiving member located on one side of the compression spring, and the lower-side spring receiving member are configured similarly and symmetrically.
