ABSTRACT:
Belt for use in a continuous variable transmission, comprising an endless carrier for taking op tensile forces, and a plurality of transverse elements moveable in the longitudinal direction along the carrier. The elements are provided with at least one saddle surface for contacting the carrier. The saddle surface defines an ultimate mutual position of the carrier and the elements relative to each other within the belt in radial direction, with a tapered lower element part including a rocking edge and an upper part extending radially beyond the carrier, when the carrier and surface are in mutual contact. Each axial end of the surface is adjoined by a limb extending predominantly in radial outward direction, thereby defining a recess open to the radial outer end of the element allowing free insertion of the carrier in the recess.
