- 摘要：
- A control structure is provided for mounting to a handle of a self-opening/closing umbrella and includes a reversal prevention wheel around which a safety rope is wound and extending through a central shaft of the umbrella with an end fixed to the reversal prevention wheel and an end fixed to a crown. A locking member that includes a pawl bar and an operation bar is arranged above the reversal prevention wheel. When The umbrella is being compressed and closed, the pawl bar engages a toothed surface of the reversal prevention wheel, whereby when errors occur in the closing of the umbrella, reversed rotation of the wheel is prevented by the pawl bar and the safety rope connected to the reversal prevention wheel is prevented from extension so as to prevent the central shaft from undesired extension and instantaneous spring back of the central shaft is also prevented.
