Claims

[Scope of utility model registration request]

A generator having a stator coil and a field coil, a battery charged by the output of the generator, and detecting the battery voltage or the generator output voltage in order to keep the battery voltage or the generator output voltage constant. In a voltage regulator having a voltage dividing resistor, a reference voltage generating circuit, and a control element that controls the field current intermittently based on the detected voltage, the voltage detecting voltage dividing resistor or the reference voltage is controlled by an external signal from the control element or a switch, etc. A voltage regulator for a vehicle, characterized in that a control element for controlling ON/OFF of a bias circuit is added to a voltage generation circuit.
