ABSTRACT:
An endless transmission belt for use in continuously variable transmissions of the chain type with a number of link plates interconnected in an endless manner. The belt has blocks spaced along the length of the belt, pins spaced along the length of the belt and engaging the blocks, and link plates arranged in sets and pins, each of the link plates having a single opening formed therein. A plurality of sets of the link plates are interconnected by the pins in an endless manner. Each link plate has horizontal portions formed in such a manner as to continue with the side end faces, thereby defining the opening, via rounded portions for contacting the pins, and first and second notches are respectively formed in the upper and lower interior edges of the horizontal portions partially defining the opening. By virtue of this arrangement, stress received by the end faces of the rounded portions of each link plate is dispersed, thereby reducing the concentration of stress in any particular portions of the link plate.
