[0002] A slanted roof usually refers to a roof with a steep slope. Due to its special structure, the windows of a house with a slanted roof also have an inclined angle. When an electric curtain is installed on such a window, the curtain motor cannot be selected from common curtain motors with a clutch structure. The clutch structure in a common curtain motor mainly functions to allow the output shaft of the gear box to drive the rotation of the output shaft, and the rotation of the output shaft will not drive the rotation of the output shaft of the gear box. Although this can allow a user to manually operate the curtain to open and close it, the curtain motor with the clutch structure cannot be applied to a slanted roof curtain. This is mainly because the track of the slanted roof curtain is inclined, and the inclination angle is usually large.
