ABSTRACT:
A drive chain belt is fitted around a V-type pulley with a pair of inclined walls movable toward and away from each other. The chain belt comprises an endless chain which is formed by pivotally connecting a plural number of rows of link members by pins. An inner extension is provided on an appropriate number or each of the link members projecting radially inward of the pulley when the chain is fitted thereon. An opening is formed in each one of the inner extension so as to fit V-blocks in the openings. Each V-block has an inclined end face adapted to be brought into engagement with the inclined walls of the V-pulley to increase the contact area to the inclined walls of the pulley. Interference portions are a provided on opposing end faces of the link members in at least one row thereof to prevent outward deflection of the chain belt beyond a predetermined angle.
