Abstract: Disclosed is a sliding window for a building, including a frame, an opening member and a motorized drive device. The device includes an electromechanical actuator, a flexible element and a pulley for winding the flexible element. The pulley is rotated by an output shaft of the actuator. One end of a first strand of the flexible element connects to a first portion of the pulley. One end of a second strand of the flexible element connects to a second portion of the pulley. The pulley and the output shaft have the same axis of rotation. The device also includes a first angle transmission mechanism engaging the first strand, so as to guide the first strand relative to the first portion of the pulley, and a second angle transmission mechanism engaging with the second strand, so as to guide the second strand relative to the second portion of the pulley.
