Abstract
The first corner portion elastically deforms in application of load such that the angle of the first corner portion changes depending on the pressing force from the first member. In this case, the first corner portion can move toward the outside of the inner periphery portion of the main body portion while the angle changes. The second corner portion has the same function as that of the first corner portion, and it can move toward the outside of the outer periphery portion of the main body portion while the angle changes depending on the pressing force from the second member in the elastic deformation of the second corner portion. As a result, the spring can prevent generation of hysteresis in load characteristics without increasing the number of parts, and enables height adjustment of the spring.
