Abstract
The present invention is directed to a portable brushcutter, which comprises a hollow tubular operating rod having a front end provided with a cutting bade and a rear end provided with a drive unit. An output shaft extends longitudinally within the operating rod to transmit a driving force from the drive unit to the cutting blade. Four or more bushings each having an elastic member are disposed in the operating rod while being longitudinally spaced apart from each other, to support the output shaft. A liner is provided to extend within the rod. The liner has a through-hole extending along the axis thereof to allow the output shaft to pass therethrough, and a radially outermost periphery formed as a plurality of strip-shaped faces circumferentially spaced apart from each other. The present invention can provide a portable brushcutter having excellent anti-vibration effect, high strength and sufficiently reduced weight.
