Abstract
A guiding belt pulley, which is configured to engage a belt with belt teeth, includes a ring configuration having a root circle at an edge thereof and a plurality of pulley teeth projected from the root circle of the ring configuration, wherein each of the pulley teeth slants related to a radial line of the ring configuration. A shift gap and a move gap are left between each pair of the pulley teeth and the belt teeth to provide spaces for the deformed belt. It may reduce a risk of disengagement of the belt and provide a safe way of power transmission.
