Abstract
A rotational angle detecting device includes a resistor of which one end is connected to the power source and the other end is grounded, a rotary potentiometer having two wipers which come into sliding contact with the surface of the resistor, a control unit which detects voltage applied to each of the wipers depending on the positions thereof upon the surface of the resistor, two resistors connected at one end to each of the two wipers, and switching means which switch the connection state between the other end of the two resistors and the power source under control of the control unit.
