A continuous driving belt, adapted for transmitting movement between two elements, each one of which is rotatable around an axis and which is provided with pins projecting in the radial direction with respect to said axis, which are adapted for insertion into corresponding holes made in the belt itself. Said belt is constructed with a primary, deformable polymeric material having a Shore-A hardness greater than 75 degrees, and is provided with a reinforcing structure that comprises a plurality of annular elements which are embedded in said primary material and which are constructed out of a secondary material that presents an elongation substantially less than that of said primary material. The annular elements lie on planes that are substantially parallel to the longitudinal plane of the mid-plane of the belt itself.
