摘要： An operating lever unit includes an operation handle (10) attached to an operating rod of an engine-powered portable working machine. The operation handle is equipped with a throttle lever (30) for regulating the power of an engine, a lock lever (40) for holding the throttle lever in a desired position, and a secondary throttle adjustment lever (37) for achieving a fine adjustment of the position of the throttle lever. To hold the throttle lever in the desired position, the throttle lever is forced against a portion of the operation handle by the action of a thrust cam mechanism (41) disposed between the throttle lever and the lock lever. For achieving the fine adjustment of the throttle lever position, the secondary throttle adjustment lever is forced by a thumb of the operator to forcibly turn the throttle lever against a frictional force acting between the throttle lever and the handle portion.
