Abstract

A vibration damper is disposed between two components (2, 3) of a portable handheld work apparatus (4). The vibration damper is held especially between a housing (6), which holds an internal combustion engine (5), and a handle (7) which is fixed on the housing (6) for guiding the work apparatus (4). The vibration damper includes a coil spring (9) and respective attachment elements (11, 12) at the ends (10, 13) of the coil spring. A coupling member (17) is provided to ensure that the work apparatus can be guided notwithstanding a break of a coil spring. The coupling member (17) projects through the coil spring (9) and bridges the axial distance (16) between the attachment elements (11 and 12). The coupling member (17) is connected to each attachment element (11, 12) so that it cannot separate therefrom.
