Abstract
A drive belt for use in a continuously variable transmission has an endless carrier and a plurality of elements. The endless carrier has a plurality of endless metal belts with plank-shaped cross sectional shapes laminated together in both radial and axial directions to form ring aggregates. The ring aggregates reduce the rigidity of the endless carrier in the axial direction and increase the allowable axial deflection endless. Thus, when off-centering occurs, the entire V-belt does not become slanted with respect to a line perpendicular to the rotational axes of the pulleys and the V-shaped blocks can be prevented from becoming tilted with respect to the pulley. As a result, the durability of the pulleys and V-shaped blocks can be improved. The entire V-belt becomes slanted when off-centering occurs in a V-belt continuously variable transmission.
