TITLE OF THE INVENTION: Filament Type Trimmer ABSTRACT OF THE DISCLOSURE: In a filament type trimmer a filament is wound on a storage spool in a rotating housing and exits through an open- ing in a rim portion of the housing. When the extending portion of the filament is rotating freely, it extends approximately radially from the housing. However, when it hits a relatively stationary object, it is deflected rearwardly so as to extend approximately tangentially from the housing. To avoid high stresses in the exiting portion of the filament, the exit opening is inclined rearwardly so that when the filament is deflected rearwardly by striking an object, it extends in a tangential line of of the spool, thereby avoiding bending stresses at the exit opening.
