A backpack-type working machine comprises an engine on a shouldering frame and a swingable arm on a side thereof. A throttle lever on the arm controls the engine. A base of the arm is connected to a holder by means of an elastic pivot means including a bolt around which the arm swings and a spring. To allow the arm to move on a plane orthogonal to a swing direction (plane including a center line of a pivot means), the holder and the base of the arm are connected such that only parts opposing and oppositely of inclined surfaces thereof are in partial contact with each other.
