A retractor for seat belt, a method of controlling the retractor, and a seat belt device. The retractor (100) comprises a stop state detection means (118) detecting that drive signals are not inputted into a power generating means (110) and a drawing direction rotation detection means (119) detecting that the power generating means (110) is rotated in the drawing direction of webbing (302). A control means (200) drivingly controls the power generating means (110) so as to rotate it in the drawing direction of the webbing (302) when the stop state detection means (118) detects that the drive signals are not inputted into the power generating means (110) and the drawing direction rotation detection means (119) detects that the power generatin means (110) is rotated in the drawing direction of the webbing (302). |
