Among a plurality of layers of metal rings, an inner circumferential projection is formed on an inner circumferential surface of at least one metal ring, and an outer circumferential projection is formed on an outer circumferential surface of the outermost metal ring. Thus, cracks extending from a surface of the metal ring can be arrested by the inner circumferential projection and the outer circumferential projection. Moreover, the outer circumferential projection of the outermost metal ring that does not abut against any other members is set to have a smaller projection height than the inner circumferential projection that abuts against other members. Thus, even if the inner circumferential projection wears by abutting against the other members, the inner circumferential projection can remain and arrest extension of the cracks; also, the projection height of the outer circumferential projection is reduced to enhance flatness of the outer circumferential surface of the metal ring.

In a driving belt configured by binding a plurality of elements in loop form by a belt-like hoop, an opening width between a first hook section and a second hook section of the element is narrower than a width of the hoop; a first width from a center to a first pillar section is larger than a second width from the center to a second pillar section; a first clearance between a saddle surface and a lower surface of the first hook section, and a second clearance between the saddle surface and a lower surface of the second hook section, are larger than a thickness of the hoop; and there is formed a weight adjusting section by which a center-of-gravity position in a width direction of the element is positioned more to a first pillar section side than the center is.

Disclosed is a steel whose composition includes specified wt % of: Ni, Mo, Co, Mo+Co+Si+Mn+Cu+W+V+Nb+Zr+Y+Ta+Cr+C+Al+B+Ti+N, Ni+Co+Mo, Al, Ti, N, Si, Mn, C, S, P, B, H, O, Cr, Cu, W, Zr, Ca, Mg, Nb, V, Ta, Y, the remainder being iron and impurities resulting from production. The inclusion population, observed by image analysis on a polished surface of 650 mm.sup.2 if the steel is in the form of a hot-formed part or a hot-rolled sheet and 800 mm.sup.2 if the steel is in the form of a cold-rolled sheet, does not include non-metal inclusions of an equivalent diameter greater than 10 m. Also disclosed are a product created from the steel, and a manufacturing method.

A metal element for continuously variable transmission and method of producing the same are provided. A rear surface of a metal element includes first contact parts formed at top positions on the outer side in the radial direction of a saddle surface on left and right sides of an ear part, a second contact part formed in a neck part, and third contact parts formed at a top position of the saddle surface on left and right sides of the body part.
