Abstract: An endless power transmission V belt is provided including a longitudinal reinforcement member formed by at least one member resistant to a tensile force such as a cable, made from a material chosen from metal, glass fibers or the like having a high tensile strength, transverse elements made from metal or another material having compression strength and an elastomer mass which integrally assembles the transverse elements together and with the longitudinal reinforcement member. The latter is blocked upright at least one transverse element by a nipping effect between said element or a part thereof and a piece cooperating therewith, such as a bar or the like, which is firmly secured thereto by appropriate means such as spot welding on the contact zones between said element and said piece, exclusively.
