A motor chamber 45 for housing the electric motor and the reducer chamber 46 for housing the reducer are adjacently formed in a power unit case 40 for housing the electric motor and the reducer by interposing a bulkhead 42b between each other. A drainage hole 96 communicating with a lower part of the motor chamber 45 is arranged in a lower part of the power unit case 40. A communication hole 97 communicating between the reducer chamber 46 and the motor chamber 45 is formed on the bulkhead 42b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
