The runner is provided with an elongated gap on its side surface and a resilient tab located outside the gap and extending downwardly from the runner base. The resilient tab has a raised portion formed on its internal surface. Users can depress the resilient tab to inwardly move a hook of the umbrella and so the runner can move downwardly with ease. The runner is an integrally molded part that has the advantages of simplified construction and safety in use.
