ABSTRACT:
In a toothed belt, each tooth of the belt in longitudinal cross-section has a tooth top part composed of a pair of tooth top portions and a tooth tip portions formed in circular arcs, respectively, whose radius dimensions and location of centers are predetermined by a set of equations and inequalities so that a first contact point of the belt tooth with a pulley groove approaches to a tooth center line. In a power transmission device using the abovedescribed toothed belt and a toothed pulley, a shape of each pulley groove of the pulley is predetermined by a set of equations and inequalities so that a compressive force applied to the belt tooth during engagement concentrates to the tooth center line.
