Abstract

A handheld work apparatus has a motor unit including a drive motor for driving a tool and a handle unit including a handle. The motor unit and the handle unit are interconnected via at least one antivibration element. A first antivibration element includes a coil spring. A first holding element is attached in a first end of the coil spring. A second holding element is attached in a second end of the coil spring. The first holding element is firmly connected to the motor unit. The second holding element is firmly connected to the handle unit. The holding elements have end faces located in an interior of the coil spring. The end faces have centering elements that can come into contact with each other and thereby center the holding elements with respect to each other. The end faces form a stop for the movement of the handle.
