Patent abstract
A tape measure includes a reel, a tape that is wound on the reel and that can be reeled out, and a hook attached to a free end of the tape. The tape includes a concave-convex shape when it is reeled out. The concave-convex shape includes a height and a width and provides rigidity for the standout length. The tape includes a flat shape when it is wound on the reel. The flat shape includes a flattened width. The maximum standout length is not larger than 100 times of the flattened width or the flatness is not larger than one fourth of the flattened width. Thus, the tape can easily be wound and flattened on the reel and will not be deformed because of change in stress when it is retroflexed or wound.
