Provided is a hybrid construction machine such that hybridization can be easily achieved even in the case of a construction machine with a super-small turning radius ratio at the rear end or a construction machine with super-small turning radius ratios (at the front and rear ends). Said hybrid construction machine is a hybrid mini-excavator with a super-small turning radius ratio at the rear end, and is equipped with an engine (11); a hydraulic pump (21) wherein an input shaft (21a) is coaxially connected to an output shaft (11a) of the engine (11); an electric generator-motor (31) wherein a rotation shaft (31a) is connected to the output shaft (11a) of the engine (11) and to the input shaft (21a) of the hydraulic pump (21), with a gear mechanism (6) therebetween; and a battery (33) which supplies power to, and receives power from, the electric generator-motor (31). The electric generator-motor (31) is disposed at a vertical position such that the lowest portion is located above the shaft center of the input shaft (21a) of the hydraulic pump (21), and at a horizontal position such that, when seen from above, the electric generator-motor (31) overlaps the hydraulic pump (21). |
