Abstract
A seat belt retractor (1) is provided which comprises a rotation sensor (8) for detecting the withdrawn amount of a seat belt, a control amount setting unit for setting a first control amount for winding up the seat belt (3) and a second control amount to which the amount reaches after the first control amount according to the winding of the seat belt (3), an electric motor (6) having a two-stage winding speed composed of at least a high speed and a low speed as the speed winding the seat belt (3), and a winding speed adjusting unit for setting the winding speed of the electric motor (6) to the high speed between the time when the electric motor (6) starts the winding of the seat belt (3) and the time when the amount reaches the first control amount, setting the winding speed of the electric motor to the low speed when the amount exceeds the first control amount, and stopping the winding action of the seat belt (3) after the amount exceeds the second control amount, thereby quickly accommodating the seat belt (3) regardless of the body size of the occupant and preventing a seat belt fixture (sic) (17) from strongly hitting a pillar or the like.
