Abstract
A webbing retractor is provided with a first variable resistor detecting a moving amount of an inner end of a spiral spring biasing a webbing takeup shaft in a direction of webbing winding, a second variable resistor detecting a moving amount of an outer end of the spiral spring and a drive control unit controlling a motor to move the outer end of the spiral spring in the direction of webbing winding or in a direction of webbing unwinding in response to signals outputted from the first and the second variable resistors. Accordingly, a tension of a webbing can be made comfortable for an occupant of a vehicle.
