Abstract
A seat belt retractor for an automobile comprises a reel for retracting a seat belt around the same, a frame for holding the reel in a rotatable manner, and a spring for biasing the reel in the direction of retracting the belt. The spring is consisted of a main spring for normally biasing the reel in the direction of retracting the belt and an auxiliary spring for producing, in the direction of retracting the belt, biasing force that is applied to the reel in an off-and-on way by an off-and-on unit, the main spring and the auxiliary spring being disposed in parallel. The device includes a unit for detecting an open/closed state of a door at the side of a seat on which the seat belt is fastened, and the off-and-on unit interrupts transmission of the biasing force in the direction of retracting the belt from the auxiliary spring to the reel when the door open/closed state detecting unit detects the closed state of the door.
