A short force arm deflection device is mounted to a section of a center post of an umbrella between a top cap and a runner and includes an upper deflection member and a lower deflection member pivotally connected to each other, and a barrel receiving a compression spring, The upper and lower deflection members are respectively connected to a lower end of an upper post segment and an upper end of a lower post segment. The barrel, receives the compression spring and goes over the connection portion between the lower deflection member and. the lower post segment. To open, the runner is pulled upwardly by a pull cord to contact the barrel causing a relative rotation between the upper and lower deflection members for realizing deflection between the top cap and the runner for inclining a canopy.
