A longitudinal discontinuity is provided in a neighborhood of the pump so as to bring the sound attenuating barrier in a backward displaced state, a blocking portion for a longitudinal discontinuity in the sound attenuating barrier is provided with through holes, pipes extending from the pump, and communicating with a hydraulic device arranged on an outer periphery side of the upper rotating body on the opposite side of the pump are laterally inserted through the through holes.
