Abstract: A tolerance ring includes a base formed of a strip-like member approximately wound around into a ring shape, and a plurality of projections provided along a winding direction of the base so as to protrude in a radial direction from an outer peripheral surface of the base, wherein each of the projections has edges serving as a boundary with the base and at least one of the edges in a width direction orthogonal to the winding direction has a shape intersecting the winding direction.

Abstract: An elliptical coned disc spring can be accommodated in a rectangular installation space, can yield non-linear load characteristics, and can reduce stress differences between a bending part at a long radial part side and a bending part at a short radial part side. An elliptical coned disc spring has a body in which an outer circumference is an ellipse in a disc shape. A hole is formed at the center of the body. The hole may have various shapes such as a circle, an ellipse, etc. The body has a long radial part 111 and a short radial part. A plate width of the long radial part is set to be greater than a plate width of the short radial part (that is, a>b).
