Abstract

A work apparatus has at least one handle (12) and a drive motor (3). The handle (12) is connected to said drive motor (3) via at least one anti-vibration element (16, 17, 18, 19, 20). The anti-vibration element (18, 19) is held on a first housing part and coacts with a second housing part. To achieve good damping, the anti-vibration element (19) includes a damping section (25) having an annularly-shaped wall (37) which expands in the direction of the second housing part.
