Abstract
A knapsack type working machine has a first frame and a second frame. A prime mover for driving a working instrument is carried on the first frame. The second frame has a back pad and shoulder straps. The first frame and the second frame are separable from each other. The first frame has a locking engagement member. The second frame engages with the locking engagement member and has a pivotal locking member urged by a spring in a direction of engagement with the locking engagement member. By releasing the locking engagement member from engagement with the pivotal locking member, the first frame is separated from the second frame.
