ベルト。[Claims for Utility Model Registration] (1) In a power transmission belt having a plurality of rib portions having a substantially trapezoidal cross section extending parallel to each other in the belt length direction on the bottom surface, the tip of each of the rib portions is parallel to the back surface of the belt. It consists of a flat tip surface and a pair of left and right corner portions, one end of which is continuous to both left and right ends of the tip surface, and the other end of which is continuous to the side surface of the rib. A power transmission belt characterized by being formed in an arcuate cross-section with a center symmetrically arranged with respect to the center. (2) The power transmission belt according to claim 1, wherein the radius of curvature R of each corner of the rib portion is set in the range of 0.17h≦R<0.5h, where h is the height of the rib portion. (3) The power transmission belt according to claim 1, wherein the radius of curvature R of each corner of the rib portion is set in the range of 0.14p≦R<0.35p, where p is the pitch interval of the rib portion.
