Abstract

A handheld work apparatus has a drive motor (8) that is held in a motor housing (2). At least one handle (4) is provided, with a vibration gap (12) being formed between the handle (4) and the motor housing (2). The vibration gap (12) permits a relative movement between handle (4) and motor housing (2). The handle (4) is connected to the motor housing (2) via at least one anti-vibration device (13, 14, 15, 16, 31, 49, 50, 63) that bridges the vibration gap (12). The anti-vibration device (15, 16, 31, 49, 50, 63) has a longitudinal center axis (23, 24). The anti-vibration device (15, 16, 31, 49, 50, 63) bridges the vibration gap (12) via at least one tension element. The anti-vibration device (15, 16, 31, 49, 50, 63) also has a spring (17, 32, 33, 51, 55, 72, 73) arranged functionally in series with the tension element.
