摘要： A continuous belt of a continuously variable transmission for transmitting a driving torque from an input pulley to an output pulley includes a plurality of blocks, links and pins. Each block includes first and second side engagement surfaces. When the continuous belt spans between the input and output pulleys, at least two different engagement points are defined between the blocks and the pulley. Each link includes first and second end portions, an intermediate portion, first and second connecting holes, an outer projection and an inner projection. The first and second connecting holes are defined within the first and second end portions. The outer projection projects from the first and end portion toward a lateral direction of the continuous belt. The inner projection projects from the first end portion in a direction opposite the direction of the outer projection. Each link has a pitch line of the link which passes through center points of the first and second connecting holes. A center line of each link passes equidistant between the outer and the inner projections. The pitch line is parallel to and spaced apart from the center line. The links are inserted into the blocks such that the outer projection of the links are positioned toward the inside of the continuous belt in one of at least two engagement points between the blocks and the pulley and the inner projection of the links are positioned toward the inside of the continuous belt in the other of at least two engagement points.
