Abstract

A handheld work apparatus includes a motor, a transmission shaft, a tool, a guide tube, a housing, and a first anti-vibration element. The motor via the transmission shaft drives the tool. The transmission shaft is received in the guide tube. The motor is disposed in the housing. The tool is disposed on a front longitudinal end of the guide tube. The housing is disposed on the rear longitudinal end of the guide tube. The housing at least partially encompasses the guide tube, wherein the guide tube projects from the housing. The first anti-vibration element is disposed such that it acts in a vibration-decoupling manner between the housing and the guide tube. The first anti-vibration element is disposed on that side of the motor facing the tool. The handheld work apparatus includes a second anti-vibration element connecting the motor to the housing in an at least indirectly vibration-decoupled manner.
