An umbrella includes a shaft with a top member connected to a top end thereof and a runner is movably mounted to the shaft. Multiple stretchers are pivotably connected between the top member and the runner. The shaft includes an inner tube and an outer tube in which the inner tube is retractably received. The runner is movably mounted to the outer tube and a stopper extends outward from an outside of the outer tube. The runner is movable over the stopper and supported by the stopper when the umbrella is opened. The shaft does not need to make a slot so as to have better strength and the inner diameter of the runner and the outer diameter of the stopper is matched so that the runner does shake. |
