An umbrella capable of adjusting a central position according to the present invention comprises: a link member for connecting an upper umbrella shaft and a lower umbrella shaft via a four-bar link method; a return spring installed on the link member to provide an elastic force to unfold the umbrella shaft linearly; a handle installed at the lower part of the lower umbrella shaft; a linear member connected to the inside of the handle from one side of the link member; a winder placed at the inner side of the handle to be able to rotate so as to wind the linear member; a rotating body for folding the link member and the upper umbrella shaft by winding the linear member around the winder in the process of providing a rotational force to the winder; a transmission member connected between the rotating body and the winder to transmit a rotational force; a stopper placed at the handle to restrict the free rotation of the rotating body; and a releasing device placed at the handle to release the linear member from the winder by releasing the winder restricted to the rotating body. Therefore, the present invention facilitates the movement of the central position because the central position of the umbrella can be moved conveniently by only rotating the rotating body placed at the handle. And the umbrella can be used for a long time as damage to components is wholly minimized because the umbrella has sufficient supporting capacity and buffering capacity. |
