Abstract

The present invention relates to an antivibration means for a power-driven, vibrating hand equipment (1), the equipment comprising a tool (3) designed to operate directly on a work area, and drive means for trans­ mitting driving energy to the tool (3). The drive means is housed in a machine housing (4) which is subjected to vibration. Vibrations from the housing (4) to the handle (2) of the equipment (1) are re­ duced with the aid of anti-vibration elements (12) arranged between these elements. To prevent vibrations from being transmitted directly from machine housing (4) to operator, the equipment (1) is provided with a protective element (14, 15) connected to the anti-­ vibration elements (12) arranged between the handle (2) and the housing (4). The protective elements (14, 15) are movable in relation to the machine housing (4) and are arranged so that it at least partially covers said housing.
