An electric oil pump capable of suppressing wear of an electric oil pump used as auxiliary to a main oil pump to thereby prolong the life of the pump and avoid any need to provide a larger pump. An electric oil pump (40) is operated only for a predetermined acceptable operation time, and the engine (12) is thereafter activated to cause the mechanical oil pump (36) to supply oil pressure. This arrangement can limit successive operating time for the electric oil pump (40), suppressing wear of the electric oil pump (40) and thus prolonging its life. Provision of a larger electric oil pump (40) can also be avoided.
