<p>An umbrella having a configuration capable of allowing its canopy or its canopy-securing part including the canopy to rotate and move naturally in an application direction of an external force applied to the canopy-securing part, whereby, even though the umbrella is bumped against another's umbrella during its use, impact transferred to them can be effectively attenuated, thereby reducing a possibility of injury and achieving a safety in use. The umbrella includes a rotating unit adapted to rotate the canopy-securing frame with respect to the umbrella shaft. The rotating unit includes a cylindrical fixed member rotatably mounted to an upper end of the umbrella shaft around the umbrella shaft, the cylindrical fixed member supporting the ribs of the canopy-securing frame, and a bearing interposed between an outer surface of the umbrella shaft and an inner surface of the fixed member and adapted to allow the fixed member to rotate smoothly with respect to the umbrella shaft. Where the umbrella is installed on the beach or rest area where there is heavy wind, it can effectively serve as an attractive advertising device by virtue of an effective rotation of its canopy or its canopy-securing part, without being easily damaged.</p> |
