Abstract
An electric power source apparatus for vehicles comprises a dynamo and a voltage regulator which includes mechanical relays, the switching of which causes high frequency noises, which in turn adversely affect a radio receiver set mounted on the vehicle. To eliminate the high frequency noises a noise absorbing capacitor is disposed between the dynamo and the voltage regulator.
