摘要： 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.

摘要： An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the right-and-left direction (R-L) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to impulses in the direction parallel to a moving direction of a cutting blade (40) operated by an operator at work.

摘要： The present invention relates to a brake band for use with a centrifugal clutch. The brake band is formed in a curved strip shape to be disposed along the outer peripheral surface of a clutch drum of the centrifugal clutch, and is adapted to be tightened around or released from the outer peripheral surface in response to the movement of at least one end of the brake band. The brake band comprises a plurality of linings provided on the inner surface thereof to be opposed the outer peripheral surface of the clutch drum. The linings are located spaced apart from each other along the longitudinal direction of the brake band.

摘要： A fuel inlet is disposed on the upper part of a fuel tank which is protruded upwardly and a connecting portion of a return pipe is located which is also protruded on the upper part of the fuel tank being separated from the fuel inlet and an air reservoir is disposed within the connecting portion of the return pipe. When fuel is poured through the fuel inlet, fuel will not go into the air reservoir. Therefore, vibrations given to the fuel tank does not cause the return pipe blocked at its lower end, allowing overflown fuel to be returned smoothly back to the fuel tank.
