Provided is a hybrid construction machine capable of facilitating the hybridization (conversion, redesigning, etc. into a hybrid construction machine) even for construction machines of the minimal tail swing radius type or the minimal swing radius type. A hybrid mini-shovel of the minimal tail swing radius type comprises an engine 11, a hydraulic pump 21 whose input shaft 21a is coaxially connected to the output shaft 11a of the engine 11, a generator/motor 31 whose rotating shaft 31a is connected to the output shaft 11a of the engine 11 and the input shaft 21a of the hydraulic pump 21 via a gear mechanism 6, and a battery 33 which receives and supplies electric power from/to the generator/motor 31. The generator/motor 31 is placed at a vertical position where its lower end is situated above the shaft center of the input shaft 21a of the hydraulic pump 21, and when viewed from above at a horizontal position where it overlaps with the hydraulic pump 21. |
