SLIDING SUN VISOR HAVING SLIM STRUCTURE

A sliding sun visor having a reduced thickness is provided. The visor includes a sliding housing provided on a sun visor body and installed to be movable in an axial direction of a pivot arm. A clamp is installed in the sliding housing to be fixed to the pivot arm and configured to guide and support a movement of the sliding housing when the sliding housing slides, in which a guide, which is a substitute for the sliding housing, is installed at an inner-upper end of the sun visor body to minimize a width of the sliding housing that surrounds the pivot arm. The guide includes a guide rail integrally formed at the inner-upper end of the sun visor body, a clamp housing moving together with the sun visor body along the guide rail, and a clamp installed in the clamp housing and sliding on the pivot arm.
