要約
(EN)

A seat belt retractor 100 includes stop state detecting means 118 which detects that a driving signal is not inputted to power generation means 110 and drawing-direction rotation detecting means 119 which detects that the power generation means 110 is rotating in a drawing-direction of a webbing 302. Here, a control means 200 controls the power generation means 110 to rotate in the drawing direction of the webbing 302, when the stop state detecting means 118 detects that the driving signal is not inputted to the power generation means 110 and the drawing-direction rotation detecting means 119 detects that the power generation means 110 is rotating in the drawing direction of the webbing 302.
