Abstract
An operational lever for a bush cutter includes a handle housed in a handle case, a throttle lever pivotally mounted to the handle, and a lock lever pivotally mounted to the handle. The operational lever further includes a torsional coil spring which exerts a resilient force on the lock lever. The lock lever is pivoted from an initial position to a pivoted position by an operator's palm. The throttle lever is then pivoted to a half-pivoted position by operator's fingers. When the palm is moved a small distance away from the handle case with the throttle lever held in the half-pivoted position, the lock lever is pivoted back towards the initial position by a resilient force of the spring. This causes a curved surface of a side protrusion portion of the lock lever to engage or abut on a side of a protrusion portion of the throttle lever. This arrangement is advantageous in that even when the operator takes her or his fingers off the throttle lever, the throttle lever is locked by a friction force produced between the curved surface and the side.
