A powered, unidirectional output controlling apparatus mounted between the main shaft of an electrically powered tool and a power source is provided. The apparatus comprises a rotating seat, a plurality of flexible disc seats made from a rubber material, a locking seat, a plurality of locking rollers and a fixing ring. One end of the rotating seat is engaged with the power source output of a power transmission mechanism and the other end of the rotating seat is provided with a plurality of insertion shafts passing through the locking seat fastened by two flexible disc seats. The locking seat is first mounted into the fixing ring. The center of the rotating seat is provided with a bolt hole for the mounting of the main shaft. The external edge of the fixing ring is secured to the housing of the electrically powered tool. The perimeter portion of the locking seat is provided with a plurality of locking slots and the locking slots are mounted with a plurality of locking rollers. During reverse transmission, the flat bottom surfaces of the locking slots push the locking rollers to engage with a narrow space at the lateral ends of the locking slots, such that the locking rollers engage with the fixing ring and the locking seat.
