Abstract
A motor housing for a string trimmer having a vibration damper disposed between the housing member and the motor. The motor housing has transverse motor support ribs fixedly supporting the motor. A damper chamber is formed in the housing between and end face and an adjacent transverse motor support rib. Stiffner ribs disposed between the end face and the adjacent transverse motor support rib form radial seats on diametrically opposite sides of the motor. A resilient linear vibration damper member is compressively received in each of the damper chambers between the electric motor and the radial seats.
