Abstract
An operation-control lever unit for regulating engine power of an engine-powered working machine to control operation of a working tool includes a throttle-lever holding mechanism operative in response to pivotal movement of a lock lever in a locking direction to frictionally hold the throttle lever at a desired position. The throttle-lever holding mechanism includes a stationary cam formed integrally with the head portion of the operator's control handle for the machine, a movable cam on the lock lever and cooperating with the stationary cam to displace the lock lever along a support shaft in a direction away from the stationary cam, and a resilient member disposed behind the movable cam and resiliently urging the movable cam toward the stationary cam.
