The present invention is to drive a hydraulic pump (12) and a generator motor (13) by an engine (10), to electrically charge a battery (20) by a generator action of the generator motor (13), and to drive the generator motor (13) by electric power of the battery (20) so as to assist the engine (10). A governor (26) position is changed by operations of a potentiometer for accelerator (21) and a mode selection (22) switch so as to control rotation speed of the engine (10). On the premise of the above configuration, generator (13) output is limited by a controller (16) at the time of accelerating the engine (10) until the rotation speed of the engine (10) reaches set speed determined on the basis of the operations of the potentiometer for accelerator (21) and the mode selection switch (22), and hence engine load is reduced so as to assist acceleration.
