PROBLEM TO BE SOLVED: To provide an operation mechanism of a power working machine where, even when a throttle lever is released from the state of being gripped by a worker hand during work, the throttle lever can be returned to the position of middle throttle opening by gripping the throttle lever again, and to provide the power working machine.SOLUTION: An operation mechanism 1x of a power working machine which is provided on an operation unit 3 of the power working machine which comprises a power unit E for actuating a working unit includes: an output control unit 8 which controls output of the power unit E through a first transmission member (10); a regulation mechanism 6 which is provided on the operation unit 3 and, by varying an initial position of the first transmission member (10), regulates the upper limit of a quantity controlled by the output control unit 8. 【課題】作業中にスロットルレバーが作業者の手で握られている状態から解放された場合でも、再度スロットルレバーを握ることにより中間のスロットル開度の位置に戻すことができる、動力作業機の操作機構及び動力作業機を提供する。【解決手段】作業部を駆動する動力部Ｅを備えた動力作業機の操作部３に設けられ、前記動力部Ｅの出力を調節する動力作業機の操作機構１ｘであって、前記動力部Ｅの出力を第１の伝達部材（１０）を介して調節する出力調節部８と、前記操作部３に設けられ、前記第１の伝達部材（１０）の初期位置を変位させることで、前記出力調節部８による調節量の上限を調整する調整機構６を有している。【選択図】図１
