[0002] A dust-proof pulley is a pulley with a dust-proof function, which includes a shaft rod and a bearing sleeved outside the shaft rod. A bearing seat is sleeved outside the bearing, and a wheel body is fixedly connected to the outside of the bearing seat. One end of the bearing seat wraps around the outside of the bearing, and the other end is fixedly connected with a dust-proof component. The bearing is pressed by a pressing ring, and at the same time, it plays a role in supporting the dust-proof cover, so that the dust-proof cover does not bear load when the pulley rotates, thus having a good dust-proof effect and effectively enhancing the service life of the pulley.
