[Problem] In a reduction and reversing gear unit 18 in which hydraulic oil is supplied to a generator motor 30 or the like as cooling oil by a hydraulic pump driven by an electric motor 73, which is separate from the generator motor 30, a problem of a noise generated by fully driving the hydraulic pump and the electric motor 73 at all time is solved by assuming a high hydraulic oil temperature when a maximum load acts on the generator motor 30.[Solution] A reduction and reversing gear unit 18 of the present invention includes an oil cooler 58 disposed in a cooling oil passage 55 that supplies hydraulic oil from an oil tank 19 to a generator motor 30 as cooling oil, a refrigerant pump 74 disposed in a refrigerant piping 72 caused to communicate with the oil cooler 58, an electric motor 73 that drives the refrigerant pump 74, and a control unit 100 that controls drive of the electric motor 73 such that a discharge amount of the refrigerant pump 74 is changed in accordance with a load detection value It of a load detection unit 101 that detects a load acting on the generator motor 30.
