An umbrella comprises umbrella ribs covered with an umbrella fabric and an umbrella frame which becomes a support of the umbrella. The present invention relates to a rotary umbrella having a simple structure in which the upper part of the umbrella frame is divided into two parts and a rotary member is coupled between the divided parts of the umbrella frame. Accordingly, the rotary umbrella allows umbrella ribs to rotate on the umbrella frame and also allows the divided parts of the umbrella frame to be stably supported while the umbrella ribs rotate smoothly. In regard to an umbrella comprising umbrella ribs covered with an umbrella fabric and an umbrella frame which becomes a support of the umbrella, the present invention relates to a rotary umbrella comprising upper and lower division end parts formed by dividing the inside of the upper part of the umbrella frame into two parts; and a rotary member inserted and coupled between the upper and lower division end parts to allow rotation of the umbrella ribs. The rotary member comprises a first rotation coupling device composed of a rotary shaft part which has a support protrusion formed in the middle of the outer circumferential surface and a rotation guiding protrusion formed on the lower part; and a second rotation coupling device having an upper end part which has a rotary shaft groove corresponding to the rotary shaft part by being coupled thereto, and a lower end part coupled and fixed to the lower division end part. |
