Abstract

The invention relates to an electrical work apparatus including an apparatus housing having an electric motor for driving a work tool, a control unit for putting the electric motor into operation, a handle housing having at least one handle for guiding the work apparatus, and a receiving cavity, realized in the handle housing, having an insertion opening for a battery pack for operating the electric motor. For the purpose of decoupling the battery pack in respect of vibration, the handle housing, together with the receiving cavity for the battery pack, is decoupled from the apparatus housing via one and the same antivibration element. A vibration gap is realized between the apparatus housing and the handle housing, wherein the antivibration element at least partly bridges the vibration gap.
