Abstract: The present disclosure relates to a pulley device, a sliding door, and a sliding window. The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.
