    Abstract: A self-supporting umbrella has a handle at a base end portion of a front shank and a ferrule at a front end portion of said shank. The ferrule includes a plurality of legs which are capable of being opened and closed. A projection which extends inward is formed inside a base end of each of the leg portions so as to pivotally mount the base end of each of the legs on a ferrule base portion. A resilient member is fitted into a front end portion of the shank such that a leg operating member having a restricted section in an axially intermediate portion thereof can be disposed on a front end of the resilient member. The restricted section is adapted to pinch therein the projection. The leg operating member is urged by a resilient force of the resilient member toward the front end of the umbrella.
