PROBLEM TO BE SOLVED: To provide a knapsack type working machine capable of enhancing damping performance. SOLUTION: A vibration control member 4 includes a fixed part 413 fixed to a frame 32, an extension part 42 extended from a working machine body 2 to a downside of the fixed part 413, and an elastic member 43 for connecting a portion 423 of the downside of the fixed part 413 in the extension part 42 and the fixed part 413, the elastic member 43 allows a spring constant of the elastic member 43 to be set to a low level compared with the case that the working machine body 2 is supported by compression because the working machine body 2 is supported by tension, and the damping performance is enhanced thereby.
