This invention relates to a wind-proof umbrella with air vents which includes umbrella frames and a cover connected on the frames. There are plurality of air vents in the cover which are spaced with each other. A rain cap is mounted over each vent to prevent rainwater from leaking. Each vent is provided with a resisting-back-turn meshwork to release wind force when wind blows upon the inside surface of the cover, which can lighten or eliminate the pressure force which wind exert on the umbrella to resist strong wind. This invention has simple structure, lower cost and is easy to manufacture. |
