PURPOSE: A driving apparatus is provided to improve the cooling efficiency of a motor by using a lubricating oil as a refrigerant. CONSTITUTION: A second refrigerant circuit(F) different to a first refrigerant circuit(L) is provided. The second refrigerant circuit(F) has a heat exchanging unit(C) of the first refrigerant circuit(L). An inverter(U) controls a motor(M). The second refrigerant circuit(F) has a cooling unit(H) for cooling the inverter(U). A driving apparatus case(10) includes a wall for adhering the inverter thereto. A flowing path of a second refrigerant is formed between the wall and the first refrigerant circuit(L). A generator(G) and the first refrigerant circuit(L) for cooling the generator(G) are provided within the driving apparatus case(10). |
