PROBLEM TO BE SOLVED: To provide a seat belt winding device and a seat belt device capable of suppressing heat generation in a motor, etc.SOLUTION: The seat belt winding device comprises: a motor; a control device carrying a motor current for driving the motor in the direction of a winding current generating a force for winding a seat belt, and reducing a current value of the motor current in the winding current direction from a first current value necessary to wind the seat belt to a second current value necessary to retain the tension of the seat belt, the control device counting current-carrying time for which the motor current flows in the winding current direction, and further reducing the current value of the motor current in the winding current direction from the second current value when the current-carrying time reaches set time.SELECTED DRAWING: Figure 2 |
