Abstract: A belt for a continuously variable transmission is provided, which is comprised of metal ring assemblies each having a plurality of endless metal rings laminated one on another, and a plurality of metal elements each having ring slots into which the metal ring assemblies are fitted, and the belt is wound around a drive pulley and a driven pulley to transmit a driving force between the pulleys. When the belt leaves the driven pulley, the metal element falls forward in the direction of advancement with respect to the metal ring assembly. For this reason, a rear end of a saddle surface of the ring slot in the direction of advancement is brought into strong abutment against an inner circumferential surface of the metal ring assembly to produce a concentrated stress, thereby shortening the life of the metal ring assembly. In order to prevent this, the radius of curvature of the rear end of the saddle surface in the direction of advancement is larger than that of its front end to reduce the concentrated stress. When the metal element is formed by a fine blanking process, the radius of curvature of the rear end of the saddle surface in the-direction of advancement is automatically increased by a punching shear drop.

Abstract: An element includes a body having a thin region in its substantially half lower portion and a head joined to the body by a neck. When the element is blanked out of a metal sheet, an excess amount of metal produced by pressing the substantially half lower portion of the body under a pressing load applied by a forming punch and a counter load applied by a counterpunch flows from the body into the metal sheet positioned on opposite side of the neck, and a metal flow is produced into laterally spaced ends of the neck. After the metal flows have occurred, the element is fully blanked out of the metal sheet by the forming punch. In the element, the head has relatively thick laterally spaced ends, and the head and the body have respective thicknesses equal to or smaller than the thickness of the head. The body includes a substantially half upper portion exclusive of the thin region, and has laterally spaced side end regions positioned on opposite side of a lower region of the neck. The laterally spaced side end regions of the body have a thickness smaller than the thickness of the lower region of the neck in the substantially half upper portion of the body.
