A power transmission belt having a flexible chain link midportion (11) defining a longitudinally continuous belt structure having opposite laterally outer side portions. Mounting elements (14,15) protrude from the side portion at spaced intervals longitudinally of the belt and side elements (16) are freely adjustably mounted one each to the protruding mounting element portions (15). The side elements define an outer surface for engaging the sidewall of a drive pulley V-groove. The invention further comprehends the provision of positioning elements (26) for retaining the side elements on the mounting elements, with the outer surfaces (17) of the side elements generally parallel to the V-groove sidewalls of the pulley for facilitating facial engagement of the side elements with the sidewall of the pulley groove when brought thereinto. |
