Abstract
A driving gear of a vehicle comprising a motor generator (MG), a power control unit () for controlling the motor generator (MG), and a case for containing the motor generator (MG) and the power control unit (). The power control unit () comprises a first inverter for driving the motor generator (MG), and a voltage converter for applying power supply voltage to the first inverter after stepping it up. The voltage converter includes a reactor (L). Heat of the reactor (L) is dissipated using lubricant touching the reactor (L) and the case as heat transfer agent. A circulation path of lubricant is formed in the case and the reactor is arranged on the circulation path.
