Abstract
A lower spring sheet has receiving portions on a sheet surface that supports a coil spring. Thus the sheet surface and a spring end portion of the coil spring come into contact discretely. The contact positions between the coil spring and the sheet surface maintain unchanged, however a undulated portion the spring end portion may have due to the manufacturing tolerance is extended when the coil spring is compressed.
