摘要： Disclosed is an improved laminated metallic belt consisting of at least two layers of an endless metallic band for use in a torque transmission device, which can transmit torque between two pulleys having variable effective radii, in combination with a plurality of metallic blocks which have surfaces contacting the innermost layer of the laminated metallic belt and are arranged along the laminated metallic belt. The metallic belt according to the present invention may be made of precipitation hardening martensitic stainless steel or maraging steel which have favorable properties as to toughness, mechanical strength and the adaptability for welding required for making an endless laminated metallic belt, but lack the surface hardness to ensure relatively favorable durability. The durability of the steel is improved according to the present invention by a nitride layer and/or an electroless nickel plating layer formed on the side edges of the endless metallic band. Optionally, the innermost and/or the outermost surface of the laminated metallic belt may be hardened in a similar manner.
