A power transmission (10) chain-belt (32) is disclosed that is especially adaptable for connecting the pulleys or sheaves (12, 14) of a pulley transmission (10). The chain-belt (32) has a plurality of interleaved sets (34) of transversely arranged links (36). Pivot means (40) joined interleaved sets (34) of links (36) to form an endless loop. At least one toe (42a, 42b) extends from each link (36) in at least some sets (34) of links (36). The toes (42a, 42b) are in opposed relationship and define a passageway (80). A plurality of struts (50) are connected to the links (36) and are positioned in the passageway (80). Each strut (50) has edge surfaces (88) for contacting the pulleys (12, 14) of the transmission (10). Each strut further includes at least one notch (52) proximate the centerline of the strut (50). Retaining links (90 ) are supported by the pivot means (40) for engaging the notch (52) and limiting the lateral motion of the strut (50) with respect to the set (34) of links (36).
