摘要： An antivibration element (1) is especially for a portable handheld work apparatus such as a motor-driven chain saw or a brushcutter. The antivibration element includes a coil spring (2) and at least one guide. An end section (7, 8) of the coil spring (2) is fixed to the guide. In order to provide a progressive characteristic line of the coil spring (2) in a simple way, the coil spring (2) has a transition section (11, 12), which borders at the end section (7, 8) and is guided with play on the guide. When the coil spring is under load, the turns of the transition section come at least in part into contact engagement with a helically-shaped slot in the guide so that the spring stiffness of the antivibration unit increases.
