The invention relates to a drive device for a furniture part that is displaceably mounted in relation to a furniture body, in particular for a drawer or similar. The device includes an energy accumulator device, which supports the displacement of the furniture part. According to the invention, the displaceable furniture part can be essentially displaced into a fully open position by the energy accumulator device, thus partially discharging the energy accumulator device. The energy accumulator device is then re-charged during the closing operation of the displaceable furniture part. The energy accumulator device only acts on part of the displacement path of the furniture part.
