An electric driver unit for an electric valve timing adjusting apparatus is disclosed. The electric driver unit includes: a motor for driving the apparatus; a switching part for applying a drive voltage to the motor; a current information output part for providing current information associated with a current flowing in the switching part; a power distribution control part for controlling power distribution to the motor by controlling the switching part; and an oil temperature information output part for providing oil temperature corresponding value, which depends on temperature of oil that surrounds the apparatus. The power distribution control part controls the current based on the current information so that the current stays below a target value. The target value includes a normal value and a large value. The power distribution control part adopts the large value as the target value until the oil temperature corresponding value reaches a predetermined temperature.
