Abstract

See full text

A disc spring which is used by arranging a plurality of the disk springs in an axial direction along a central axis includes an annular body plate portion that has an inner peripheral surface and an other peripheral surface which gradually extend toward one side in the axial direction from an outside toward an inside in a radial direction, and a stopper portion that protrudes from the body plate portion in a direction intersecting the inner peripheral surface and the outer peripheral surface of the body plate portion, in which in a case where an axial compression load is applied to a spring member in which a plurality of the disc springs are arranged in the axial direction, the stopper portion abuts another disk spring adjacent in the axial direction or a support member supporting an axial end portion of the spring member, the body plate portion and the stopper portion are integrally formed, and both axial end edges of the stopper portion are positioned inside both axial end edges of the body plate portion in the axial direction.
