Vibration damper

The invention relates to a vibration damper between a housing (4), which holds an internal combustion engine, and a handle (3) fixed on the housing (4). The handle (3) is for holding and guiding the motor-driven chain saw (2) during use thereof. The vibration damper (1) is a coil spring (5) which is...

Beschreibung
Zusammenfassung:	The invention relates to a vibration damper between a housing (4), which holds an internal combustion engine, and a handle (3) fixed on the housing (4). The handle (3) is for holding and guiding the motor-driven chain saw (2) during use thereof. The vibration damper (1) is a coil spring (5) which is fixed at a first end (10) thereof with an attachment element (7) to the handle (3) and, at a second end (20), the coil spring is fixed with a further attachment element (30) to the housing. A part turn of the end (10, 20) of the coil spring (5) is held form-tightly to the attachment element (7, 30) in the direction of its longitudinal center axis (25). To provide a torsion-free assembly of the coil spring, it is provided that the coil spring (5) can be assembled from one of its ends (20) between the handle (3) and the housing (4) and be secured at least at one of its ends (20) to the attachment element (30) against a rotational movement in the peripheral direction.
