PROBLEM TO BE SOLVED: To provide a seat belt winding device and a seat belt device which can suppress drawing of a seat belt without a sensor for detecting the drawing of the seat belt.SOLUTION: A seat belt winding device and a seat belt device include a motor, and a control device which reduces a duty ratio of a pulse width modulation signal for controlling a drive voltage of the motor to a second value smaller than a first value from the first value necessary for winding the seat belt. The control device reduces the duty ratio from the first value to the second value, and increases the duty ratio at an increasing rate which defines an increase amount of the duty ratio per unit time so as to suppress the drawing of the seat belt.SELECTED DRAWING: Figure 2

    【課題】シートベルトの引き出しを検出するセンサが無くても、シートベルトの引き出しを抑制できる、シートベルト巻き取り装置及びシートベルト装置の提供の提供。【解決手段】モータと、前記モータの駆動電圧を制御するパルス幅変調信号のデューティ比を、シートベルトの巻き取りに必要な第1の値から前記第1の値よりも小さな第2の値に減少させる制御装置とを備え、前記制御装置は、前記デューティ比を前記第1の値から前記第2の値に減少させてから、前記シートベルトの引き出しが抑制されるように、前記デューティ比の単位時間当たりの増加量を規定した増加率で前記デューティ比を増加させる、シートベルト巻き取り装置及びシートベルト装置。【選択図】図2
